This year marks the 25th anniversary of the release of their full-length album and to celebrate the occasion, the album will be re-released on September 30, 2016 in a deluxe package that will feature previously unreleased demos, live material, alternate takes and concert video. And although the members of the Seattle alt rock supergroup have played a handful of legendary shows back in the early 90s and a couple of reunion appearances over the years, this year will also mark the first time that the act has gone out on a headlining tour.

“Black Cat,” was a previously unreleased demo that finally sees the light of day, and as you’ll hear it’s a propulsive and percussive, bluesy dirge that pairs Cornell’s signature wails with grimy blues power chords in a song that manages to channel Led Zeppelin and Soundgarden’s “Spoonman.”
