Thin Lizzy are worshipped by rockers of every stripe. While the band's slashing boogie lives on in Guns N' Roses' epic sleaze-rock jam “Paradise City,” their Irish romanticism haunts U2's passionate post-punk anthem “Two Hearts Beat As One.” As for the act's use of twin leads, Mastodon's “Sleeping Giant” takes it to the next level, agilely weaving axes into bruising yet complex prog metal.
