Vampire Weekend debuts new song titled "Unbelievers"

Watch Vampire Weekend perform a new song titled "Unbelievers" on "Jimmy Kimmel Live," wearing Halloween makeup.

from Huffpo: Two years after the group's sophomore album, "Contra," made a No. 1 debut on the Billboard charts, Vampire Weekend premiered a new song on Wednesday night. The verdict? As good as ever. 

The band revisited the old favorite "Oxford Comma" for a web-only broadcast, too.
