Caliban is a German quintet whose metalcore is truly a crushing entity to behold. With a bevy of stage and recording experience under its belt, Caliban seems poised to overthrow the current leaders of all that is heavy, and with riffs as heavy as "Vicious Circle" and "The Seventh Soul", it just may happen quicker than you'd think. SHADOW HEARTS is an album guaranteed to pound the hell out of your speakers, as the 11 tracks that comprise this disc are as relentless as Candiria, Hatebreed and Poison the Well combined. How's that for heavy? Working around a few different metal influences without slaving over just one, Caliban in turn makes a brutally well rounded disc while maintaining its own identity, one of the toughest things to pull of in the metal realm.
