Melvins are said to be "the Godfathers" of grunge music. Melvins were the first post-punk band to revel in the slow, sludgy sounds of Black Sabbath. Their album Houdini was released in 1993. In 2005 the album was performed live in its entirety as part of the All Tomorrow's Parties-curated Don't Look Back series. Melvins were one of Kurt Cobain's favorite bands; he is given co-production credit alongside Melvins on six tracks.
