Chris Cornell made a surprise appearance last night at a Pearl Jam show in Los Angeles, the former Soundgarden singer r with Eddie Vedder, Jeff Ament, Stone Gossard and ex-Soundgardener/current Pearl Jam drummer Matt Cameron (note the awkward hug between those two) as grunge supergroup Temple of the Dog. Together they plowed through karaoke/life staple “Hunger Strike.”

Also of note, Jerry Cantrell of Alice in Chains came out for “Alive.” Sweet christ, that’s a lot of grunge.
