Soundgarden are currently working on their themselves are set to release new studio effort next year. Lead guitarist Kim Thayil revealed that the band would like to make its upcoming album sound different from the previous recordings. Earlier drummer Matt Cameron claimed that the effort would feature reworked versions of several tracks they have written long ago, but never released.

However, Kim Thayil said it did not mean the album would be based on Soundgarden's classic sound. "We want to make sure the material excites us. The last thing we want to make is another grunge or metal record", claimed he.
