Nirvana were a largely unknown band when they entered Reciprocal Recording studio in Seattle in late 1988 to cut their debut LP, Bleach. Though they had yet to perform a show outside of Washington state, they signed a deal with indie label Sub Pop and cut the album in just 30 hours over a period of a couple weeks. Cobain later claimed to have written most of the lyrics the night before the first session. The album didn't find much of an audience at first, but after the band blew up with Nevermind, fans went back to find their first release. A deluxe edition came out in 2009 in honor of the 20th anniversary.
