Tomorrow, Soundgarden roar back with 'King Animal,' their first studio album since 1996, and tonight (Nov. 12), they'll celebrate their return with a 'Live on Letterman' webcast concert at the Ed Sullivan Theater in New York City. The performance -- available for streaming below -- kicks off at 8PM EST, shortly before the grunge titans appear as musical guests on 'The Late Show With David Letterman.'

Formed in 1984, Soundgarden helped lead the Seattle invasion of the '90s. The group scored a string of mainstream hits, including 'Spoonman' and 'Black Hole Sun,' but by 1997, they'd run their course. They reconvened in 2010, and in a recent interview with the QMI Agency, Blabbermouth.net reports, frontman Chris Cornell explained how he and his bandmates went from revisiting their back catalog to writing the next chapter in their storied career.

"It was a matter of us being in a room together and then becoming comfortable and starting to take on a responsibility for reconnecting with our fans based on our old material and considering doing reissues," Cornell said. "And that led to us finally deciding to play a show and then tour and then a new album."
