Epi and Vampire Weekend on Jimmy KimmelVampire Weekend dressed up for Halloween and performed a new song on Jimmie Kimmel Live on Wednesday.  The new track, "Unbelievers," will be officially released soon.

“We’ve been working like maniacs for a long time," Ezra Koening told Consequences of Sound. "The time is not so far away, we promise.” Ezra revived their breakaway hit "Oxford Comma" performing on an Epiphone Sheraton II.  (Watch for the expletive parents because your kids already know it's there!)
