Noise pop

Noise pop is a term used to loosely describe a number of alternative rock bands that fuse punk rock's attitude and anger with the atonal noise, feedback, and free song structures of noise music, presented in a decidedly pop context. Psychocandy by The Jesus and Mary Chain, released in 1985, is often considered to be the album that defined and launched the genre.
