Rock band F.T. Island is back with its new EP “Lock Up” after a hiatus of over two years.

The band will drop its eighth EP “Lock Up” on Friday at 6 p.m. along with the music video for its lead track “Unthinkable.”

This is F.T. Island’s first music since its three members — Lee Hong-gi, Lee Jae-jin and Choi Min-hwan — finished their mandatory military service.

F.T. Island debuted in 2007 and is best known for hits such as “Love Sick” (2007) and “Severely” (2012).
