Soundgarden with singer Chris Cornell started work on their upcoming studio album on September 2. With Chris Cornell and Matt Cameron jamming on guitars, the band released a photo or it on their Facebook account on September 2. The caption beneath it read, "Working on new material this week."

In a recent interview with Rolling Stone, Chris Cornell discussed Soundgarden's next record which is the followup to 2012's King Animal. However, while on Pulse Radio, he said that they're working on it in a "relaxed pace".

Chris Cornell said, "We're already working on new material for an album," Chris Cornell also said, "And then I've got several other irons in the fire and things going that I won't mention now. There's a lot of things coming in addition to Higher Truth, as well as a new Soundgarden album."

In a recent interview with Zane Lowe's on Beat 1, the singer discussed what he has learned from the break-up and the current status of the band. Lowe asked Cornell, "if it feels like there's an open door when it comes to Soundgarden, and if they they ca come back anytime they want, and if they've already crossed that bridge."

He confirmed that indeed they feel like there's an opportunity for them to work together again, especially with the album Higher Truth coming along the way, the acoustic tours they will be having to support it and the songwriting involved in it.

When asked about the break up, he told The Pulse on Radio, that it was actually good for the band members to work on their own projects for a time, as they become more creative in their work when they get together again.  They brought in  whatever good they have learned from the experiences they've encountered outside.

"We all bring in our outside-the-band experiences back in, and that doesn't seem to ever be anything but a good thing," he said. "It's great to sort of go out into a different world and come back with new understandings of how to write songs and how to record albums, and also just that sort of palate-clearing of doing something different."

"Higher Truth", Cornell's fourth solo studio album, will be released on September 18 and features the single "Nearly Forgot My Broken Heart".

He  will begin a solo acoustic tour in support of "Higher Truth" on September 18 in San Diego, winding down on November 4 in Phoenix.
