The Strokes frontman Julian Casablancas surprised audience members Tuesday night when he snuck onstage in a Win Butler mask during an Arcade Fire show.
Arcade Fire has taken to wearing large paper mâché bobblehead-style masks in recent months, and their show last night at Lollapolooza Argentina was no exception. The band had started to sing their song "Normal Person" before the real Win Butler ran on stage and unmasked the imposter.
