Cube Entertainment's newest face, BtoB, just released their debut title tracks!

As previously announced, the group will be promoting double title tracks: "Insane" (a dance track), and "Imagine" (a ballad).

The rookie group left fans speechless with their recent release of the two tracks. The boys continued to impress on today's episode of 'M! Countdown,' where they performed both "Insane" and "Imagine".

Check out their live stages below, and be sure to check out the rest of today's performances from 'M! Countdown' here (coming soon)!
