With blistering shows and tree-shredder vocals, this UK trio personified punk attitude, even before punk broke in England. After cutting his teeth in hard prog-rockers Hawkwind, Lemmy Kilmister launched Motörhead in 1975, and was its only constant member until his death in 2015. They recorded a head-spinning array of killer albums, all showcasing a ferocious brand of sucker-punch rock, while pioneering genres like speed metal and thrash along the way. Everyone from Guns N' Roses to Slayer have sung Motörhead's praises, but Dave Grohl put it best: "Lemmy's the king of rock 'n' roll".
