Stewart Armstrong Copeland was born in Alexandria, Virginia on July 16, 1952, the youngest of four children of Alabama-born CIA officer Miles Copeland Jr. and Scottish archaeologist Lorraine Adie. The family moved to Cairo, Egypt, a few months after his birth, and Copeland spent his formative years in the Middle East. In 1957, his family moved to Beirut, Lebanon, and Copeland attended the American Community School there. He started taking drum lessons at age 12 and was playing drums for school dances within a year. Later he moved to England and attended Millfield boarding school in Somerset from 1967 to 1969. Copeland went to college in California, attending United States International University and the University of California, Berkeley. Returning to England, he worked as road manager for the progressive rock band Curved Air’s 1974 reunion tour, and then as drummer for the band during 1975 and 1976.

Copeland was romantically involved with Curved Air vocalist Sonja Kristina beginning in 1974, and they were married from 1982 to 1991. Copeland adopted Kristina’s son Sven from a prior relationship, and they had two more sons together, Jordan and Scott. In 1981, Copeland fathered a son, Patrick, with Marina Guinness, daughter of Irish author Desmond Guinness. Copeland currently lives in Los Angeles with his second wife, Fiona Dent, with whom he has three children (Eve, Dylan and Celeste).

In early 1977, Copeland founded the Police with lead singer-bass guitarist Sting and guitarist Henry Padovani (who was soon replaced by Andy Summers), and they became one of the top bands of the 1980s. The Police’s early track list (before their album debut) was largely Copeland compositions, including the band’s first single “Fall Out” (Illegal Records, 1977) and the B-side “Nothing Achieving”. Though Copeland’s songwriting contribution was reduced to a couple of songs per album as Sting started writing more material, he continued to co-arrange all The Police’s songs together with his two bandmates. Amongst Copeland’s most notable songs are “On Any Other Day” (where he also sang lead vocals), “Does Everyone Stare” (later to be used as the title of his documentary on the band Everyone Stares: The Police Inside Out), “Contact”, “Bombs Away”, “Darkness” and “Miss Gradenko”. Copeland also co-wrote a number of songs with Sting, including “Peanuts”, “Landlord”, “It’s Alright for You” and “Re-Humanize Yourself”.

Copeland also recorded under the pseudonym Klark Kent, releasing several UK singles in 1978 with one (“Don’t Care”) entering the UK Singles Chart that year, along with an eponymous 10-inch album on green vinyl released in 1980. Recording at Nigel Gray’s Surrey Sound Studio, Copeland played all the instruments and sang the lead vocals himself. Kent’s “Don’t Care”, which peaked at No. 48 UK in August 1978, actually predates the first chart single by the Police by several months (“Can’t Stand Losing You”, issued in October 1978) as “Don’t Care” was released in early June 1978.

Copeland grew up listening to a combination of Lebanese music, rock and roll, jazz, and reggae, but he selected from these styles what he needed rather than imitating them. In the 1980s, when many musicians were looking for bigger sound from bigger drums, he added Octobans. Invented by Tama Drums in 1978, Octobans consisted of eight six-inch drums in the shape of narrow tubes. He used another innovation, a splash cymbal based on a toy that he owned and that he helped Paiste design. He relied heavily on his 13″ hi-hats.

In 1982, Copeland was involved in the production of a WOMAD benefit album called Music and Rhythm. Copeland’s score for Rumble Fish secured him a Golden Globe nomination in 1983. The film, directed and produced by Francis Ford Coppola from the S. E. Hinton novel, also had a song released to radio on A&M Records “Don’t Box Me In” (UK Singles Chart n. 91)—a collaboration between Copeland and singer-songwriter Stan Ridgway, leader of the band Wall of Voodoo—that received significant airplay upon release of the film that year.

The band attempted a reunion in 1986, but the project fell apart.

Copeland also occasionally played drums for other artists. Peter Gabriel employed Copeland to perform on his song “Red Rain” from his 1986 album So because of his “hi-hat mastery”. He has also performed with Mike Rutherford and Tom Waits. That year he also teamed with Adam Ant to record the title track and video for the Anthony Michael Hall movie Out of Bounds. In 1989, Copeland formed Animal Logic with jazz bassist Stanley Clarke and singer-songwriter Deborah Holland. The trio had success with their first album and world tour but the follow-up recording sold poorly, and the band did not continue.

In 1993 he composed the music for Channel 4’s Horse Opera and director Bob Baldwin. In 1999, he provided the voice of an additional American soldier in the animated musical comedy war film South Park: Bigger, Longer & Uncut (1999).

He was commissioned by Insomniac Games in 1998 to make the musical score for the hit PlayStation game Spyro the Dragon. Copeland would play through the levels first to get a feel for each one before composing the soundtrack. He also stayed with the project to create the musical scores for the remaining Insomniac sequels Spyro 2: Ripto’s Rage! and Spyro: Year of the Dragon. The franchise shifted over to Universal for the fourth title, Spyro: Enter the Dragonfly, which would be Copeland’s last outing with the series. While the soundtracks never saw commercial release, the limited edition of the fourth game came packaged with a bonus CD, containing unused tracks. The soundtracks were very well received, and one track would later appear on the 2007 compilation album The Stewart Copeland Anthology.

This period also saw Copeland compose the soundtrack for Alone in the Dark: The New Nightmare, his only video game soundtrack outside of the Spyro franchise to date. In 2000, he combined with Les Claypool of Primus (with whom he produced a track on the Primus album Antipop) and Trey Anastasio of Phish to create the band Oysterhead. That same year, he was approached by director Adam Collis to assemble the score for the film Sunset Strip.

In 2002, Copeland was hired by Ray Manzarek and Robby Krieger of the Doors to play with them for a new album and tour, but after an injury sidelined Copeland, the arrangement ended in reciprocal lawsuits. In 2005, Copeland released “Orchestralli”, a live recording of chamber ensemble music which he had composed during a short tour of Italy in 2002. Also in 2005, Copeland started Gizmo, a new project with avant-garde guitarist David Fiuczynski, multi-instrumentalist Vittorio Cosma, singer Raiz and bassist Max Gazzè. The band made their U.S debut on September 16, 2006 at the Modern Drummer Drum Festival. In January 2006, Copeland premiered his film about The Police called Everyone Stares: The Police Inside Out at the Sundance Film Festival. In February and March, he appeared as one of the judges on the BBC television show Just the Two of Us (a role he later reprised for a second series in January 2007).

At the 2007 Grammy Awards, Copeland, Andy Summers and Sting performed the song “Roxanne” together again as The Police. This marked the band’s first public performance since 1986 (they had previously reunited only for an improvised set at Sting’s wedding party in 1992 and for their induction into the Rock and Roll Hall of Fame in 2003). One day later, the band announced that in celebration of The Police’s 30th anniversary, they would be embarking on what turned out to be a one-off reunion tour on May 28, 2007. During the tour, Copeland also released his compilation album The Stewart Copeland Anthology, which was composed of his independent work.

In 2007, the French government appointed Copeland (along with Police bandmates Summers and Sting) a Chevalier of the Ordre des Arts et des Lettres.

The group performed 151 dates across five continents, concluding with a final show in August 2008 at Madison Square Garden, New York.

In 2008, RIM commissioned Copeland to write a “soundtrack” for the BlackBerry Bold smart phone. He created a highly percussive theme of one minute’s length from which he evolved six ringtones and a softer ‘alarm tone’ that are preloaded on the device.

In March 2008, he premiered his orchestral composition “Celeste” at “An Evening with Stewart Copeland”, part of the Savannah Music Festival. The performance featured classical violinist Daniel Hope. His appearance at Savannah included a screening of Everyone Stares: The Police Inside Out and a question and answer session. Also in 2008, he was commissioned by the Dallas Symphony Orchestra to create a percussion piece involving primarily Indonesian instruments. “Gamelan D’Drum” was first performed in Dallas on February 5, 2012 and had its European Premiere at the Royal Academy of Music in London in July 2012.

Copeland’s eldest brother, Miles Copeland III, founder of I.R.S. Records, was the manager of The Police and has overseen Stewart’s interests in other music projects. Stewart’s other brother, the late Ian Copeland, was a pioneering booking agent who represented The Police and many others. His father, Miles Copeland, Jr., was a founding member of the Office of Strategic Services (OSS) and the Central Intelligence Agency (CIA), according to his 1989 biography and files released by the CIA in 2008. Despite his occasional references to “Uncle Aaron”, Copeland is not related to the composer Aaron Copland.

On August 21, 2009, at SummerFest 2009, Copeland unveiled the composition “Retail Therapy”, which was commissioned by the Music Society. He performed three more original works: “Kaya”, “Celeste”, and “Gene Pool”, the last accompanied by San Diego-based percussion ensemble red fish blue fish. He attended a composer’s roundtable and a question and answer discussion in conjunction with the festival. Copeland wrote the score for a theatrical presentation of Ben-Hur, which premiered on September 17, 2009, at the O2 Arena in London. He provided English-language narration of the production, which is performed in Latin and Aramaic. His memoir Strange Things Happen: A Life with The Police, Polo, and Pygmies was released by Harper Collins in September 2009. The book chronicles events in his life from childhood through his work with The Police and to the present. In October 2009, he was a guest on Private Passions, the biographical music discussion program on BBC Radio 3.

On May 24, 2011, he started a YouTube channel devoted to his videos and project updates. On this channel, he uploads performances with various musicians, including Primus, Andy Summers, Jeff Lynne, Snoop Dogg, and others in his home studio, which he refers to as the Sacred Grove. On August 24, 2011, he was a featured soloist on the Late Show with David Letterman, as part of their second “Drum Solo Week”.

On January 10, 2012, he appeared on an episode of the A&E reality series Storage Wars to appraise a drum set for Barry Weiss, buying a Turkish cymbal from the set for $40. In July he reunited with former Animal Logic bandmate Stanley Clarke for a European tour.

In May 2013, he and the Long Beach Opera premiered The Tale Tell Heart, an opera based on the short story by Edgar Allen Poe.

On November 26, 2013, he appeared in the first episode of The Tim Ferriss Experiment.

In 2017, he formed the supergroup Gizmodrome with Adrian Belew, Vittorio Cosma, and Mark King and released an album of the same name.

On June 25, 2019, The New York Times Magazine listed Stewart Copeland among hundreds of artists whose material was reportedly destroyed in the 2008 Universal fire.
