Superunknown

Superunknown is the fourth studio album by American rock band Soundgarden, released on March 8, 1994, through A&M Records. Produced by Michael Beinhorn and the band themselves, Soundgarden began work on the album after touring in support of their previous album, Badmotorfinger (1991). Superunknown retained the heaviness of the band's earlier releases while displaying a more diverse range of influences.

Superunknown was a critical and commercial success and became the band's breakthrough album. It debuted at number one on the Billboard 200, selling 310,000 copies in its opening week. The album also topped the Australian, Canadian, and New Zealand charts.

At the 37th Grammy Awards, the album was nominated for the Grammy Award for Best Rock Album. It has been certified 6× Platinum by the Recording Industry Association of America (RIAA) in the United States. Superunknown has been listed by several publications as one of the best albums of the 1990s and a quintessential grunge album. In April 2019, it was ranked No. 9 on Rolling Stone's "50 Greatest Grunge Albums" list.
