After a 17 months hiatus, Taiwanese singer Danson Tang (???) is now back with a new album and what better than to return with a title song called I'm Back. For his grand comeback, Danson had learned L.A. Style dance moves for nearly three months from a dance teacher and his record company has even gone on further by inviting f(x)'s Amber to do the rap for him. Amber had flew to Taiwan despite being in the midst of promotions with f(x) back in Korea to record the song and also film a music video. And because Amber is able to speak Mandarin, they were able to communicate their ideas with each other and got on together well. They also gave their own albums to each other as gifts and promised to work together again in future if there's another opportunity. The song was finally unveiled through Hit FM on the 2nd, so check it out below. Stay tuned for the release of the music video on June 10th. http://www.youtube.com/watch?v=ZVGWVUWbnLI Check out the MV promo teaser. http://www.youtube.com/watch?v=GCIKhGB_pjU Many thanks to Hadi for the tip.
