You really should make it a point to listen to the entire Sylvan Esso album, which came out a couple of years ago. ‘Coffee’ was their big number, but the rest of the LP is full of songs that are equally striking. ‘Wolf’ is such a laid back track, and really shines during the chorus, which is so damn catchy despite having no words. I’m pretty sure that’s supposed to sound like a wolf howling. I mean it’s in the name. If you are a fan of the Postal Service and are growing increasingly impatient waiting for their 2nd album, then this should feed your appetite until then.
