"Blew" was written in 1988 by Nirvana front man Kurt Cobain. The song was recorded in December 1988 and initially appeared as the first track on Nirvana's 1989 debut album Bleach. In addition to the song "Blew", the release also includes "Love Buzz". This mix of "Love Buzz" is the Bleach version, as opposed to the 7" Sub Pop Singles version mix. The version of "Been a Son" that was recorded for the EP is hailed as the "definitive take" of that song as it encompasses Nirvana's thrashing signature sound as well as Krist Novoselic's bass guitar solo being much more pronounced in the mix. "Stain" features both dual vocal and dual guitar tracks.
Blew was released in December 1989 on Tupelo Records on 12" vinyl and compact disc. The extended play was originally intended to be released to promote an upcoming European tour, but this plan was scrapped, and the maxi-single ended up being released exclusively in the UK shortly after its completion.
As Blew was released only in the UK it was thus difficult to obtain elsewhere. Only 3,000 copies of the maxi-single were pressed on 12" vinyl and CD. Both vinyl and CD counterfeit copies exist, of which the vinyl copies vary in colour (the official 12" vinyl was only pressed on black vinyl).
Video footage the aforementioned 1991 performance in Amsterdam later appeared on the Nirvana DVD re-release of Live! Tonight! Sold Out!! in 2006.
A live performance of the song, from the 1992 Reading Festival, was released on the Live at Reading CD and DVD release in 2009.
Another live performance, recorded February 9, 1990 at The Pine Street Theatre in Portland, Oregon, appears, with the rest of the concert, as the last track on the 20th anniversary deluxe reissue of Nirvana's 1989 debut album Bleach in 2009.
