On March 8, 1994, Soundgarden unleashed their fourth album, 'Superunknown,' a now-ironic title considering the great heights the disc has reached.

Perhaps Soundgarden's greatest disc, the effort yielded a number of the popular grunge act's most beloved songs.

'Superunknown' featured Chris Cornell and company taking a major step in their career, as singles such as 'Spoonman,' 'Black Hole Sun' and 'Fell on Black Days' enjoyed massive success at rock radio. The album reached No. 1 on the Billboard 200 chart and has sold 5 million copies in the United States alone.

In addition to its commercial success, 'Superunknown' was met with universal critical acclaim, receiving a nomination for Best Rock Album at the 1995 Grammy Awards.
