Having established themselves as one of the hottest rookie acts to debut in 2012 and sweeping up various awards, B.A.P is kicking off 2013 with a track called "Rain Sound"!

The song, described as an emotional hip hop track, serves as the pre-release off of their upcoming mini album in February, and is once again the work of Kang Ji Won, who has worked on B.A.P's "Warrior" along with various hits from SECRET, and Marco, who lent his efforts with their song, "No Mercy".

Despite it being only a pre-release off their upcoming mini album, it's said TS Entertainment has invested quite a bit into the music video for the track to bring in ambulance trucks and high speed cameras with 2,000 frames per second to capture the smallest details.
