By the time of the album's release, bassist Nick Oliveri, also a former member of Kyuss, would join the band.  "Queens of the Stone Age" received generally positive reviews from critics, who placed it in the stoner rock genre and drew comparisons to krautrock bands such as Can and Neu!  as well as to Kyuss and other metal bands.

Kyuss: Kyuss ( ) was an American rock band, formed in Palm Desert, California, in 1987 by Josh Homme (guitar), John Garcia (vocals), Brant Bjork (drums) and Chris Cockrell (bass).  After releasing an EP under the name Sons of Kyuss in 1990, the band shortened its name to Kyuss and recruited Nick Oliveri, replacing Cockrell as bassist.  Over the next five years the band released four full-length albums, and one last split EP in 1997 as Kyuss and the newly formed Queens of the Stone Age.  This tied up the loose ends of Kyuss and introduced the new band Queens of the Stone Age, which was initially composed entirely of former Kyuss members.

After the release of the EP, Homme received a cease and desist order because the name Gamma Ray was already in use by a German band.
