Grunge elder gods Soundgarden released King Animal, a better album than anyone expected, last year, and they apparently still have some fire left in them. They’ve had a big few days. Last night, they played President Obama’s Inaugural Ball (check out photos above). And on Saturday night outside Philly, they debuted yet another new song — a slow-building, droning jam led by Chris Cornell’s acoustic guitar. Watch a fan-made video below; the as-yet-untitled new song starts around 3:30.

King Animal is out now on Seven Four/Republic.
