Soundgarden’s drummer says band is mixing an eight-song final album built from demos started in 2013

Soundgarden is in the final stages of mixing a planned eight-song album that will feature vocals by the late Chris Cornell, according to an interview with drummer Matt Cameron published by Billboard on July 30.

Cameron said the record is being constructed from demos that the band’s members began working on in 2013, a timeline that places the project’s origins well before Cornell’s death.

In describing the production process, Cameron said getting to the current point has taken time, characterizing it as “kind of a long process just to get to here.” He indicated the band had to assemble and refine earlier material so it could be presented as a coherent release rather than left as unfinished recordings.

The project follows the band’s long-running legacy as a major rock act whose catalog helped define mainstream alternative radio in the 1990s and 2000s. While Soundgarden’s public-facing activity has varied over the years, the existence of new, Cornell-vocal tracks has continued to draw attention from longtime fans and the broader music industry.

The record’s current status appears to be limited to mixing at the time of the report, meaning it has not yet reached the stage where details such as a release date, track listing, or distribution approach are confirmed in the Billboard report.

Cameron’s comments place emphasis on archival groundwork by the band rather than a last-minute revival. By building the album from work started in 2013, the project relies on material that was created while all members were able to participate in the early stages of development.

For audiences, the near-term focus is on how the finished album will be prepared and presented, including how the band and its production team handle demo sources, vocal integration, and final sound decisions. For the industry, any release built from earlier demos also raises the practical question of how estates, rights holders, and production teams coordinate on timelines large enough to ensure consistency and accuracy.
