Soundgarden played a one-off show over the weekend at New Orleans' Voodoo Music Experience Festival and were joined by Corrosion of Conformity and Down's Pepper Keenan for the song 'Gun.'

Soundgarden are currently working on a new album, which marks their first in nearly 15 years. According to the latest conversation vocalist Chris Cornell had with Billboard, the album expected next spring may be closer than we think:

"It's mostly done. We just need to finish a couple of songs and mix it, so that will be happening probably over the holidays."

While the world anxiously awaits the band's return to the forefront of hard rock, Cornell will be displaying his softer side on his 'Songbook' tour. When asked if he planned to preview any new Soundgarden material at upcoming solo dates, the singer explained that he didn't want to "take [the songs] out of context yet." Guess we'll have to wait for the Adam Kaspar-produced album's release next spring...or earlier (fingers crossed).

The band didn't debut any new songs while performing in New Orleans either, but they did deliver an old tune in a new way. Soundgarden was joined by COC frontman and Down guitarist Pepper Keenan while they played 'Gun' from their second album 'Louder Than Love.'
