After 27 months since making their debut, 2AM finally released their 1st studio album, "Saint O'Clock", and they continued with promotions on the October 30th episode of Music Core. The boys do not deviate much from their ballad roots of the past, as their two comeback tracks, "You Wouldn't Answer My Calls" and "Like Crazy", are of that flavor. Still though, each performance has been designed to give fans a different audio-visual experience. Check out the performances below, and get serenaded by them again!
