BoA participated in the making of the Original Soundtrack for an upcoming KBS drama 'Shark' which will feature actress Son Ye Jin as the lead female character.

BoA recorded "Between Heaven and Hell," one of the OSTs included in the drama.

A slow ballad based on waltz with lyrics that reminisces pains of heartbreak, "Between Heaven and Hell" brings out the best of BoA's other side many fans often forget due to her spectacular dance moves on stage: the soulful, emotion-wreaking vocals.

The song will be released on May 27 and featured in the premiere of 'Shark' on the same night.

Meanwhile, Boa will hold a concert on June 1 at 'BoA Special Live 2013 Here I Am' in Busan, Korea.
