With only two “official” full-length albums to their name, Frankie Goes to Hollywood hardly seems like the kind of band to warrant a two-disc retrospective, but between the myriad remixes, B-sides, and epic album cuts, ZZT’s Frankie Say Greatest dutifully sums up the career of one the U.K.’s most enigmatic collectives. While the pillars of Frankie’s time on earth will always be “Relax,” “Two Tribes,” and “Power of Love,” it’s hard not to get swept up in all of the nihilist fervor, even as the aforementioned singles are milked over and over again for every last drop of drug-induced, dancefloor-ready, anarchic splendor.
