When We Rock, We Rock and When We Roll, We Roll

Acting as a condensed primer to the development of Deep Purple’s supple heavy rock, When We Rock draws from the band’s 1968 freakbeat origins (“Hush,” “Kentucky Woman”) and depicts their Hulk-like transformation into a monstrous, riffing ball of muscular tension (“Burn”). “Smoke On the Water” and “Space Truckin’” are ample proof of their rolling juggernaut power, while “Woman from Tokyo” showcases their pin-sharp sense of dynamics.
