Montano was born in Carenage (Northwestern Trinidad) on 24 November 1974 and his family moved to Siparia (Southwestern Trinidad), when he was very young. He attended Siparia Boys’ R.C., then Presentation College, a prestigious secondary school in San Fernando, where he was in the choir led by Mrs Cynthia Lee-Mack. Machel first shot to fame as a nine-year-old boy with the song “Too Young To Soca” while he was still in primary school. In 1984, along with his older brother Marcus and neighbours, the group Pranasonic Express was started and, in 1989, the band became Xtatik. In April 1986, at the age of 11, Montano appeared on the mainstream television show Star Search. In 1987, he took part in the Trinidad and Tobago National Song Writers Festival, and placed second with his song “Dream Girl”. He also won the Caribbean Song Festival in Barbados, becoming the first Trinidadian and youngest contestant to win this competition.

Montano is the front-man of the soca band The HD Family. In 1987 he was the youngest finalist to ever win the Caribbean Song Festival. His career spans more than 30 years. Around 2012 he moved to the Los Angeles area. He is very well known in New York City, where he has had sold-out concerts in Madison Square Garden many times over. Machel is a six time international Soca Monarch.

In the United Kingdom, he co-presented the International Sounds of Soca show on the BBC’s black music digital radio station BBC Radio 1Xtra for four years with DJ Slic. His successful singles, with and without Xtatik, include “Big Truck” (Xtatik’s most successful single, which won the Road March title in 1997), “Outa Space” (with Beenie Man), “Music Farm” (Xtatik), “It’s Carnival” (with Destra), and his Road March title wins in 2006, “Band Of The Year” (with Patrice Roberts), and in 2007, “Jumbie”.

The band developed and was re-invented by its leader Montano several times, including as The Xtatik Circus, Xtatik The Road Marching Band and The Band of the Year. Since 2007 they have been known as Machel Montano HD (High Definition); Montano promoted the concept by saying that he is the first human being to go HD. He claims this characterizes the evolution of his music over the past 25 years and the highly improved style in which his music is presented to his fans in radio format, television, and during live performances. He is part of a campaign in Trinidad and Tobago to promote safe driving – “Arrive Alive”. Part of the hype surrounding Montano since 2007 is his HD tour bus, a 20-year-old bus from the Public Transport Service Corporation (PTSC) that was re-done and includes a bedroom, bathroom facilities, flat-screen TVs, Internet access and expensive audio systems. After its debut in 2007, the bus was re-painted for 2008, the new images of Machel matching various photos from the album artwork of his 2008 CD, Flame On. The bus featured heavily in his videos for “Jumbie” (2007) and “Rollin/Blazin d Trail” (2008). In 2012 Montano won the Road March, Power Soca Monarch and the Groovy Soca Monarch. He won the Groovy Soca Monarch with his rendition of “Mr. Fete”. In May 2012 he launched the music video to his hit single “Bottle Of Rum”.

His album Flame On, released in February 2008, featured collaborations with calypso artistes David Rudder on “Oil and Music” and Mighty Sparrow on “Congo Man”. Flame On also includes Clamydia with other artistes from various genres including soca, reggae, rap and reggaeton. Examples of these partnerships can be heard on the following tracks: Patrice Roberts on “Rollin”, Shaggy on “Wining Season”, Buju Banton on “Make Love” and finally Lil Jon and Pitbull on “Defense (The Anthem)”.

The International Soca Monarch competition is an annual contest between various competing Soca artists. Within this competition there are two sub-categories which contestants can place in. One of which is the Power Soca Monarch; a competition for upbeat songs while the International Groovy Soca Monarch is for Soca songs of a slower tempo. In 2011, Montano won his first Soca Monarch competition (from Power Soca Monarchs) for his performance of the song “Advantage”. In the years 2012 and 2013, he won back to back times in both sub-categories for his performance of his songs “Pump Yuh Flag” and “Mr. Fete”, in 2012 and, “Float” and, “The Fog”, in 2013, winning TT$2 Million each time. He also won the Power Soca Monarch in 2014 for his song “Ministry of Road”, however he was dethroned by Kerwin Du Bois and his hit song “Too Real” in the Groovy Soca Monarch category. Montano set a new record by winning the 2014 Power Monarch, becoming the first artist/ performer to win a total of four titles. He won the title again in 2015 with his hit song “Like Ah Boss”.

On 20 January 2013 Montano released the official video for the single “The Fog” from his 16th solo album, “Machelements”. On 27 January 2013, Machel then released another video for his single “Float”. Two days after another visual was released for his song “Happiest Man Alive”. Other songs that were followed by immediate visuals are “Epic”, taking two months to create and release, and “Ministry of Road”, taking less than one month to follow up on.

In 2014, Montano took an interest in electric dance music (EDM), collaborating with EDM artists Major Lazer to create EDM song with a Soca vibe, called “Sound Bang”.

In November 2014 Montano won a Soul Train Award for Best International Performance for the song “Ministry of Road (M.O.R.)”. His win for “Ministry of Road” is the second consecutive win at the BET Soul Train Music Awards for Soca Music just after Bunji Garlin won in 2013 with Differentology.

On 21 January 2019 Montano released the single “The Road”. The song features R&B Ashanti.

On February 14, 2020 Montano married his longtime girlfriend Renee Butcher (now Renee Montano) at Trinidad’s The Red House, the first such wedding in 20 years at the country’s seat of parliament.
