Drumgasm is the human pileup of three superstar drummers: Janet Weiss (Sleater-Kinney, Wild Flag, Quasi), Zach Hill (Death Grips, Hella), and Matt Cameron (Pearl Jam, Soundgarden). Earlier this summer, we’d learned that all three went into a room together to record a tribal, intense improvisational record, and now, that clattering half-hour beast of a thing is out online for all to hear. You can stream the entire single-track monster, and read an interview with Weiss about it, at SPIN.

Drumgasm is out 8/27 on Jackpot.
