Hip hop duo Untouchable begins their promotions for their new song "You You" on Inkigayo today before their official enlistment together later this year. After making several hip hop hits since their debut in 2008, the duo opted for something different this time by creating a fusion of hip hop and rock. Their title track, "You You", was produced by hit composer Kang Ji Won (who produces for SECRET, Song Ji Eun, B2ST, 4minute) and Kim Ki Bum. The song features a refreshing electric guitar that brings out the depth of Untouchable's impeccable rap skills, and with the added effect of real drum sounds, the song takes on a powerful and dynamic feel. TS Entertainment trainee Oh Jin Suk also makes an impressive debut by adding his vocal talent to the mix.
