After a break of nearly two years, Vampire Weekend returned to the stage on Thursday night at the House of Blues in Cleveland. The Brooklyn-based band debuted an upbeat, as-yet-untitled new song at the show, presumably off the band's forthcoming third album. "Obviously we haven't been rushing it," bassist Chris Baio said of the new album to Rolling Stone in April. "We take it very seriously. We'll be incredibly psyched to share it with the world when it's done." They'll be hitting Chicago on Sunday to headline the Pitchfork Music Festival.
