Eddie Vedder makes surprise appearance during The Strokes’ Seattle show opening for RHCP

The Strokes opening for Red Hot Chili Peppers is already a pretty stacked bill, and that’s before Eddie Vedder joined in on the fun.

The Pearl Jam frontman made a surprise appearance during Julian Casablancas and company’s support set in Seattle Wednesday, joining them for a rendition of their 2005 single “Juicebox.”

Fan-shot footage of the onstage collaboration was posted by YouTube user supercones. Come for the music, stay to watch Vedder’s hip-shaking dance moves.

The Strokes will be opening for Red Hot Chili Peppers for the remainder of their U.S. headlining tour, which will conclude September 18 in Arlington, Texas. The bill also includes acclaimed bassist — and recent Gorillaz collaborator — Thundercat, as well as King Princess for select shows.

The Chili Peppers are touring in support of their new album, Unlimited Love, which dropped in April. The “Can’t Stop” group will release their second record of the year, Return of the Dream Canteen, on October 14.
