Rock music is about many things, but in its purest form, I think it's often about performing rock music. The showmanship of rock is baked into its musical DNA, and that's especially true of the early hard rock era of the '70s, where the bombastic arrangements and aggressive, virtuosic technique were intrinsically married to wild costumes and elaborate stage shows that transformed bands from mere performers into ringleaders of their own audience circus. And perhaps no song captures that marriage quite like The Ballroom Blitz, an explosive rock song about how explosive rock shows can be, inspired by real events and transforming the studio recording into a proxy for the wild experience of an actual live gig.
