2008—present: Solo career establishment
After contributions to singer Lexy's album, Taeyang was scheduled to release a solo album. Initially scheduled for a September release, the project was pushed back due to conflicting schedules with his group.[4] Taeyang released his debut mini-album Hot on May 22, 2008, backed by a production team that included Teddy, Yang Hyun Suk, Kush, and his fellow member G-Dragon.[nb 1] 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".[4] 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 express his "thoughts and ideas."[4]
The first single released was "Only Look At Me" (Korean: 나만 바라봐), an R&B song written by Teddy and Kush. Taeyang stated that the lyrics come from the perspective of a man who is "selfish" for wanting his girlfriend to be with him only, regardless of how he treats her.[9] G-Dragon later recorded a "Part Two" version to the song. The second single was "Prayer (Korean: 기도)" which featured Teddy of 1TYM. Promotional videos were shot for both. In support of his album, he also staged his first solo concert, Hot.[10] Later on, Taeyang 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.[11]
Throughout the majority of 2009, Taeyang contributed to his group's activities, recording the song "Lollipop" with his group and labelmate 2NE1. He later flew to Japan to promote the group's Japanese albums. After activities ended, he went back to the studio to record and release his first digital single "Where U At",[12] followed by another digital single, "Wedding Dress". Promotional videos were filmed for both "Where U At" and "Wedding Dress." "Wedding Dress" was voted #3 on an online poll for a Dutch radio station.[13]
Taeyang's first full-length album Solar was released on July 1, 2010. Two versions of this album - the “Regular Edition” and the “Deluxe Edition” - was released. The regular edition contained 11 songs, while the deluxe edition, limited to 30,000 copies worldwide, had 13 songs, including “Only Look At Me” and “Prayer" from Hot. On the first day of sales for the limited deluxe edition, the 30,000 copies released by YG entertainment were sold out in online and offline stores.[14] The album was later released on iTunes,[15] charting at the number-two spot on the iTunes' Top R&B-Soul albums chart in the United States and number-one in Canada, making him the first Asian musician to do so.[16] Two singles were released for promotion: "I Need A Girl" featuring his bandmate G-Dragon and "I'll Be There."
