It’s understandable that someone like Mike Watt, former bassist of legendary punk band Minutemen, would have a bevy of celebrity musician friends. But his performance at the Triple Door last night was an unprecedented throwback to Seattle’s grunge years when Eddie Vedder (of Pearl Jam), Dave Grohl (of Foo Fighters and Nirvana), and Pat Smear (also of Foo Fighters and Nirvana) joined Watt onstage for a 10 minute-long jam session. The stunt was a huge surprise for everyone, but it’s not the first time Watt has worked with some of these grunge superstars. Back in the mid-nineties, he recruited Vedder and Grohl to be his touring band after the release of his first solo album, Ball-Hog or Tugboat? Check the video below to see Watt rock out with Grohl on drums, Smear on guitar, and Vedder on vocals and guitar.
