Pearl Jam frontman Eddie Vedder dropped in on a recent set by Tangiers Blues Band in New York City, during a charity benefit.
Vedder joined the group for a rendition of Jimi Hendrix's arrangement of "All Along the Watchtower."
It was a night of star features for Tangiers Blues Band, as they were also joined onstage by Jackson Browne for a song.

Vedder is a longtime friend of Tangiers Blues Band harmonica player and renowned rock and roll photographer Danny Clinch.
Bruce Springsteen also attended the TriBeCa, New York, event. He took the stage at one point in the night to thank the Fund for all their work over the past 25 years.
Vedder has kept busy since Pearl Jam entered the Rock and Roll Hall of Fame last year. He's toured solo, with his band and he's even done some busking outside of Chicago's Wrigley Field.
Pearl Jam will get back on the road this summer, but the band will also be busy fighting homelessness for the rest of the year.
After returning from a tour of South America and Europe, Pearl Jam will play two "home" shows at Safeco Field in Seattle.
The band announced that it would donated at least $1,000,000 from each of the Seattle shows at the 48,000-seat ballpark to fight local homelessness.
Over the next year, Pearl Jam's goal is to raise $10 million in the fight against homelessness.
The band will also celebrate America's past-time this summer by putting on a string of monster hard rock shows at several baseball stadiums around the country. Following the "home" Seattle shows, Pearl Jam will perform at "away" ballparks in Montana, Illinois and Massachusetts.
