Last night in Seattle, a quartet of local luminaries gathered on the rooftop of the famous local landmark Pike Place Market to pay tribute to punk rock overlords Iggy & The Stooges. The band was all heavy hitters: Mudhoney frontman Mark Arm, Pearl Jam guitarist Mike McCready, Screaming Trees/Mad Season/Skin Yard drummer Barrett Martin, and remarkably well-preserved Guns N’ Roses bassist Duff McKagan, who’s allowed to count as grunge because he’s from Seattle and he was in the Fastbacks. Together, they played a set of seven Stooges songs as a fundraiser KEXP’s new home campaign. Watch a bunch of videos below.

If anyone is going to manage the impossible task of being a tribute band’s Iggy Pop, Mark Arm is the guy you want for the job.
