Kid A was released in 2000 and was a turning point for Radiohead and an influence on many of the Alt/Indie groups that followed. It was more experimental than previous releases and incorporated a lot of unconventional sound, as well as conventional instrumentation used in unconventional ways. Kid A was itself influenced by Electronica, jazz, and Rap. Horns and strings were freely used and resulted in a sound that alienated some veteran fans.
Peter Gabriel: Radiohead have been one of my favourite bands for a long time – they’re brilliant and bold in their composition, experimentation and always seem drawn to new challenges.
