According to Naver, Taeyang's album will be a full album (not a mini) and is scheduled to be released in either August or September. It will be produced by YG Entertainment's rising producer and 1Tym Member Teddy. Currently, Teddy is busy working on 2NE1's album but he'll immediately shift his full focus over to Taeyang once the work on 2NE1's album is complete.
Taeyang enjoyed much success during his solo release last summer. And I believe he'll find even more success again this time around. No word on G-Dragon's solo album, but it looks like it's been pushed to the back burner for now.
