Jon Stewart, Amy Schumer Top Clusterfest Lineup

Jon Stewart and Amy Schumer will headline Comedy Central’s second Clusterfest comedy and music festival, set to take place June 1st through 3rd at the Civic Center Plaza and Bill Graham Civic Auditorium in San Francisco.

The event’s stacked lineup will also feature the live debut of the Lonely Island, the musical-comedy troupe of Andy Samberg, Jorma Taccone, and Akiva Schaffer. The trio – who have released three studio albums, two movies and a slew of music videos – helped announce the Clusterfest lineup with a video that offered a journey inside Samberg’s stomach.
