The project that Krist Novoselic of Nirvana and Matt Cameron of Soundgarden and Pearl Jam have teased on social media the past few weeks is called 3rd Secret.
And they're joined in the project by Soundgarden guitarist Kim Thayil, guitarist Bubba Dupree (who was in a band called Hater with Cameron) and vocalists Jennifer Johnson and Jillian Raye, who were in Novoselic's Giants in the Trees project.
The group's self-titled debut was released to all streaming services. There's no word yet if a physical release is planned. The group has already done one secret show at Seattle's Museum of Pop Culture, but more tour dates are unlikely because of Cameron's Pearl Jam touring commitments this year.
