Mudhoney is the debut studio album by American grunge band Mudhoney, released in 1989. It was their first LP after several singles and an EP (Superfuzz Bigmuff). The instrumental song "Magnolia Caboose Babyshit" is a cover of "Magnolia Caboose Babyfinger" by Blue Cheer, but the song is still credited to Mudhoney. The album, when bought as a new vinyl record, is also packaged with a poster of the band (Photo by Michael Lavine). The poster features the band in a blue filter and says "Mudhoney. The album is out." as well as the SubPop and Au Go Go logos.
