Bleach is the debut studio album by American rock band Nirvana, released on June 15, 1989, by Sub Pop. After the release of their debut single "Love Buzz" on Sub Pop in November 1988, Nirvana rehearsed for two to three weeks in preparation for recording a full-length album. The main recording sessions for Bleach took place at Reciprocal Recording in Seattle, Washington between December 1988 and January 1989. It is the only Nirvana album released on the Sub Pop label and their only studio album to feature drummer Chad Channing.

Nirvana was an American rock band formed in Aberdeen, Washington, in 1987. Founded by lead singer and guitarist Kurt Cobain and bassist Krist Novoselic, the band went through a succession of drummers, most notably Chad Channing, before recruiting Dave Grohl in 1990. Nirvana's success popularized alternative rock, and they were often referenced as the figurehead band of Generation X. Despite a short mainstream career spanning only three years, their music maintains a popular following and continues to influence modern rock culture.
