David Bowie was a master at mixing saucy rock 'n' roll with bits of funk, soul, and R&B, then distilling it perfectly in a live setting. Whether in character as Ziggy Stardust or the Thin White Duke, or playing it straight, the glam-rock godhead could shift effortlessly on stage between a composed croon and a sleazy strut. There's no escaping his dance-floor booms and strident riff rockers.
