Initially dismissed as a one-hit wonder, Radiohead evolved into one of the world's most acclaimed bands thanks to a willingness to tread where few had gone before. The angsty Britpop of 1995's The Bends first signaled that the Oxford quintet were a unique proposition. But it was 1997's OK Computer, an ambitious, pre-millennial blend of prog rock and electronic music, that elevated them to the realm of all-time greats. From the chart-topping minimalism of Kid A to the abstract art rock of The King of Limbs, they have consistently pushed boundaries ever since.
