A veritable jukebox of the classic rock that Def Leppard grew up on in '60s and ’70s England, this covers album sees the multi-platinum rockers paying tribute to their (mostly British) influences with muscular covers of T. Rex, Thin Lizzy, The Sweet, and a rousing version of Mott the Hoople’s “The Golden Age of Rock 'N' Roll.” Elsewhere, tasteful and understated takes on David Bowie’s “Drive-In Saturday” and The Kinks’ “Waterloo Sunset” dial down the bombast in favor of soulful melodies.
