Born and raised in Uijeongbu, Gyeonggi-do, South Korea, Dong Young-bae’s first contact with music was playing the piano, where he enjoyed classical music composed by Ludwig van Beethoven and Franz Schubert. When his family began struggling financially, Dong felt the need to find a job to help support them at a young age. In sixth grade, he auditioned and won the part of “mini Sean” in Jinusean’s music video “A-yo”, where he was introduced to and became fascinated with hip hop music. On the occasion, Dong met Yang Hyun-suk CEO of the record label YG Entertainment and begged him for a chance to become a singer. As he got no answer, he went to his office personally to achieve his intention. Yang gave him the opportunity to audition, where he was successful, and accepted by the record label as a trainee. There, he met fellow trainee and future bandmate Kwon Ji-yong. Dong spent the first few years as a trainee cleaning the studio for the other artists in the company and fetching them water bottles during dance practices, later admitting that current artists at the time weren’t friendly towards him or Kwon. In 2003, Dong provided the rap verse in singer Wheesung’s single “Player” on the latter’s second album.

After contributing to singer Lexy’s album, Taeyang announced that he was going to release a solo album. Initially scheduled for a September release, the project was pushed back due to conflicting schedules with his group. Instead, Taeyang released the EP Hot in May 2008, backed by a production team that included 1TYM’s Teddy Park, Yang Hyun Suk, Kush, and his fellow member G-Dragon. Moving beyond the hip-hop genre of Big Bang, Taeyang incorporated mainly R&B songs into his album, stating that it was his “main focus”. He expressed disappointment with the album, however, admitting that he did not write any of the songs. He later stated that he would do so in the future to fully express and incorporate his thoughts and ideas into his music. The EP produced two singles: “Only Look at Me” (Korean: 나만 바라봐, Revised Romanization: Naman Barabwa), an R&B song written by Teddy and Kush, and “Prayer (Korean: 기도; Revised Romanization: Gido)” which featured Teddy. Promotional videos were shot for both. In support of his album, he also staged his first solo concert, the Hot Concert Series. Taeyang later received two awards from the 7th Korean Music Awards: Best R&B/Soul Song for “Only Look at Me” and Best R&B/Soul Album for Hot.

Taeyang’s first full-length album Solar was released in July 2010 in two versions: a “Regular Edition” and a “Deluxe Edition”. The regular edition contained eleven songs while the deluxe edition, limited to only 30,000 copies, had 13 songs, including “Only Look at Me” and “Prayer” from Hot. The “Deluxe Edition” sold out on the first day of release. Two singles were released for promotions: “I Need a Girl” and “I’ll Be There”. In Solar, Taeyang contributed to its production; composing, co-writing four songs (“Solar”, “Where U At”, “Wedding Dress”, and “Take It Slow”) and writing lyrics for “Take It Slow”. Taeyang won the “Best Male Artist” award at the 2010 Mnet Asian Music Awards. Both the regular and the deluxe versions peaked at the number one position on the Gaon Album Chart.

In 2010, a part of Taeyang’s income of albums, goods, tickets and digital music sales went for donation as a part of With campaign by YG Entertainment. Taeyang’s fans donated IS$5,180 on May 15, 2014, under Taeyang’s name to The May 18 Memorial Foundation in celebration of his birthday. The following year, they donated water wells to help provide clean water to communities in need in the Southeast Asian countries of Cambodia and Myanmar, they have been donating what they named as “Taeyang’s water” for three straight years through the international charity organization Worldshare.

Throughout his career, Taeyang has sold an estimated 10 million records, making him one of the best-selling male South Korean R&B artists. On November 23, 2010, Taeyang was presented with an award for his contribution to pop culture at the 2010 Korea Popular Culture and Arts Award Ceremony held by the South Korean Ministry of Culture, Sports and Tourism. In 2017, he was appointed as an honorary ambassador for the 2018 Winter Olympics in Pyeongchang, being one of the Hallyu stars tasked with extolling the virtues of South Korea for the world. Taeyang has earned two Golden Disc Awards, three Korean Music Awards, including Male Musician of the Year by Netizen Vote in 2011, three Melon Music Awards and four Mnet Asian Music Awards. His song “Eyes, Nose, Lips”, released in 2014, won Song of the Year in all major Korean awards, including Gaon Chart Music Awards, Golden Disc Awards, Melon Music Awards, and Mnet Asian Music Awards, making him the first R&B solo artist to do so.

The release of his first full-length album, Solar, was the first K-Pop music release to be sold worldwide on iTunes as both an audio and video album. The audio version hit iTunes stores on August 19, 2010, while the video version arrived by September 10, 2010. His second album Rise is debuting at number 112 on Billboard 200 chart.

Taeyang took two years to record new materials and participate in promotional activities with Big Bang for their Korean EPs Tonight (2011) and Alive (2012) as well as the Japanese studio album Alive (2012). When activities wrapped up, he turned his focus back to preparing for his second studio album. The single “Ringa Linga” was released in November 2013, preceding his second album Rise (2014). While he utilized the help of Teddy Park, G-Dragon, and Choice37, Taeyang also involved himself with its production, producing six tracks. Rise became the third highest charting K-pop album, and also the highest charting K-pop album by a solo artist on the Billboard charts, reaching 112 on the Billboard Hot 200 while topping the Billboard World Albums Chart and Heatseekers Albums Chart, selling 3,000 copies. In Japan, the album ranked at number two, with 48,000 units sold. Taeyang released another two singles to promote the album: “Eyes, Nose, Lips” and “1AM.” The former became his first chart topper on the Gaon Digital Chart while the latter peaked at number seven. The choreography for “Ringa Linga” spawned numerous covers on the video-sharing website YouTube, while “Eyes Nose Lips” was covered by various celebrities, including label-mates Akdong Musician, Tablo, Lydia Paek as well as Korean singer Eric Nam and Canadian pop star Michael Bublé. Comedian Yoo Jae-suk also parodied it on the popular variety program Infinite Challenge. “Eyes, Nose, Lips” was the second best-performing single of 2014 in South Korea.

Taeyang then embarked on the Rise World Tour in support of the album, visiting 9 countries and 16 cities in Asia beginning in August 2014. The tour concluded in early 2015 with an attendance of over 100,000 fans. At the 2014 Mnet Asian Music Awards, Taeyang won Best Male Artist, Best Vocal Performance and Song of the Year for “Eyes, Nose, Lips”.

Taeyang collaborated with G-Dragon in November 2014 to release the song “Good Boy” for YG Entertainment’s new hip hop project. The song received positive reviews, with Fuse naming it one of best songs of the year, and debuted at the number one position on Billboard’s World Digital Songs chart, the third time a Korean act topped the list and the first for a male group. The music video on YouTube currently boasts over 100 million views.

For two years from 2015 to 2016, Taeyang toured extensively with his band for their third Korean album, performing for over 3.6 million fans in two years. In 2015, Taeyang participated in the biennial Infinite Challenge music festival, with bandmate G-Dragon. The duo teamed up with ZE:A’s Hwang Kwanghee and released the single “Mapsosa”, which peaked at number two on the Gaon Digital Chart. The same year, he appeared on Mnet’s Show Me The Money as a featured singer on labelmate Song Min-ho’s single “Fear”, composed by Zico during the semi-finals which became one of the best-selling singles of the year.

Taeyang’s voice is highly praised for its tone. Korean critic Kim Young-dae called his timbre “luxurious and one you couldn’t find before him,” noting that “instead of giving off a mechanically trained and cold aura that other idols usually exhibit, he has a warm and full emotional range.” In 2015, Taeyang was voted the third best K-Pop male vocalist by music industry officials. He was described as a “feline” and ferocious live performer by The New York Times. Once described to have “moves like Chris Brown [and] smooth vocals like Miguel,” The Straits Times highlighted “his vocal prowess and sex appeal” as the best traits of his performances, and claimed that his free-styled moves show off “why he is often crowned the dancing king of K-pop.” A review of his first solo tour stated that:

In January 2017, YG Entertainment announced that Taeyang is working on his new album, alongside solo concerts. Taeyang commenced his second world tour, White Night, with stadium concerts in Japan. The first two shows were held at Chiba Marine Stadium and were attended by 50,000 people, which was followed by two shows at Kobe Sports Park Baseball Stadium. The tour is set to visit 19 cities around the world, including stops in North America, with concerts in eight cities across Canada and the United States.

Taeyang’s third studio album, White Night, was released on August 16, 2017 with dual lead singles “Darling” and “Wake Me Up”. “Darling” became a Top 10 hit on the Gaon Digital Chart while “Wake Me Up” managed to chart at number five on Billboard’s World Digital Songs. Additionally, the album debuted at number one on the Billboard’s World Digital Albums, and remained the following week atop this chart, making Taeyang the second solo K-Pop artist to have an album do so. In South Korea’s Gaon Album Chart, the album peaked at number three, with over 57,000 copies sold in August.

He has been in a relationship with actress Min Hyo-rin since 2013. In December 2017, it was confirmed by their respective agencies that they planned to marry in February 2018. On February 3, 2018, Taeyang and Min married in a private ceremony with family and friends, officiated by actor Ki Tae-young.

In 2017, Taeyang started endorsing auto maker Lexus, becoming the brand’s Korean ambassador for their newest model LC500h, composing and writing the lyrics for the promotional song “So Good”, which was released in May. Taeyang partnered with Italian fashion house Fendi to design an exclusive capsule collection line “Fendi for Taeyang” which features an array of T-shirts, hoodies, jackets, accessories and sneakers – with Taeyang’s signature daisy-shaped motifs and positive words like, “Faith”, “Grace”, “Saved”, and “Passion”. The collection is set to debut in Hong Kong on July 27 with the prices ranging from $447-$9,490.

Taeyang began his 21 months of mandatory military service on March 12, 2018 by entering the 6th Infantry Division’s boot camp in Cheorwon, Gangwon Province as an active duty soldier. He was discharged on November 10, 2019 along with fellow Big Bang member, Daesung.
