Grunge icons Soundgarden have been working on their comeback album ever since they reunited in 2010. While the band could have easily rested on their laurels and released another Superunknown or Down on the Upside, they insist that the new record won't be a trip down memory lane.

Speaking to Billboard, frontman Chris Cornell stated that the new LP is almost complete and should be out early next year.

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

Cornell continues: "It's certainly not nostalgic. It's definitely forward. It sounds to me exactly like it should sound -- like we took a break and we got together and we're making an album. I don't think we've taken any dramatic new approaches to writing or recording, and yet there's definitely changes."

The singer credits Soundgarden's 13-year hiatus as a reason for the renewed energy in making new music. It sounds odd but also makes a lot of sense.

"We've all had a decade-plus of more experience in writing and recording and took a long break," Cornell explains. "So it's very refreshing and it feels to me like the next logical step in Soundgarden, creatively."

Soundgarden's new album is expected to drop in stores next Spring. In the meantime, Chris Cornell will release his solo album Songbook on November 22. The musician is touring the country playing acoustic versions of classic Soundgarden, Audioslave and Temple of the Dog songs, as well as original material. Cornell will stop by the State Theatre in Kalamazoo on December 6.
