"Blew" is a song by American rock band Nirvana, written by vocalist and guitarist Kurt Cobain.

The Bleach version of "Blew" was accidentally recorded one step lower than the band had intended, which contributed to what Nirvana biographer Michael Azerrad called its "extraordinarily heavy sound".

[6][7] "Blew" was one of only three songs from Bleach, along with "About a Girl" and "School", that remained in the bands setlists until the end of their touring career.

It was performed live for the final time in Munich, Germany on March 1, 1994, as the second-to-last song preceding "Heart-Shaped Box".

The cover art was photographed by Cobain's then-girlfriend Tracy Marander at a May 26, 1989 concert at the Green River Community College in Auburn, Washington.

The Blew version of "Been a Son", hailed by Kurt St. Thomas as the "definitive take" due to its trashy sound and pronounced bass solo,[17] remained a rarity until it was re-released in October 2002 on the band's first best-of compilation, Nirvana.
