As JamBase points out, the man jumped on stage during the band’s performance of “Bust It Big”. He began screaming and lunged at several different members of the band — at one point, he crashed into drummer Todd Nance’s kit and appeared to hit Nance in the face with his drum sticks.
According to JamBase, the concert was paused for several moments as members of the band went backstage to compose themselves. However, they were ultimately able to finish the set.
