Released in December 1989, 6 Months after the release of the bands debut album Bleach, Blew was intended to be used as a promotion for the upcoming European tour. However, this plan was scrapped and the EP was released exclusively in the United Kingdom by Tupelo Records.
It was originally released on both 12" vinyl and CD although only 3,000 copies were ever pressed. This limited number and the land-locked release makes finding an original copy very difficult indeed. Modern reissues were pressed on both coloured vinyl and picture discs (of the cover) although the original 12" release was only pressed on black vinyl.
Blew is made up of 4 tracks which are alternate versions of tracks that appear on other albums. 'Blew' and 'Love Buzz' both appeared on Bleach whilst 'Been a Son' and 'Stain' later appeared on Incesticide.
