Last night, Vampire Weekend performed a new song “Unbelievers” on Jimmy Kimmel Live with their faces painted for Halloween. “Unbelievers” has Vampire Weekend’s signature sound that sounds like perfectly calculated math. You know what I’m talking about, their songs sound like culture and math. It’s hard to explain, so just listen and you’ll know what I mean, and if you don’t, then you’re just not smart enough for their music. ZING!
