The 'Modern Vampires' -- i.e. Vampire Weekend -- swarmed 'the City' (that'd be Manhattan) this past Saturday night (May 11), taking to the 'SNL' stage to perform two songs from their forthcoming album, 'Modern Vampires of the City.'

The appearance marked Vampire Weekend's third time on the show, and that's a pretty impressive feat in and of itself. After a vigorous introduction from host and former cast member Kristen Wiig, the band played the new song 'Diane Young.' The lively run-through, complete with saxophone and a dazzling light show, likely woke up anyone dozing while viewing.

The boys returned for a second time to deliver a rousing rendition of 'Unbelievers.' Again, they they rocked it, getting some help from some horn-playing friends. Check out both tunes below, and keep an eye out for 'Modern Vampires,' which lands tomorrow (May 14).
