Soundgarden release Ultramega OK

Ultramega OK is the debut studio album by the American grunge band Soundgarden, released on October 31, 1988 through SST Records.

Following the release of the EPs Screaming Life (1987), and Fopp (1988), both for the Sub Pop record label, Soundgarden signed with the independent record label SST and went to work on its first full-length studio album.

The resulting album contained elements of heavy metal, psychedelic rock, classic rock, and hardcore punk. The band supported the album with a tour of the United States as well as its first overseas tour. In 1990, the album earned a Grammy Award nomination for Best Metal Performance.
