Delta Spirit: Bushwick Blues & White Table (live)

WTMD favorites Delta Spirit check in with a pair of live tracks. "Bushwick Blues" has a slower tempo than the original, which amplifies the folk influences, "White Table" begins with a solitary slide guitar and builds to an explosion of twangy feedback. Be sure to enter their contest, you could win a signed maraca!

Buke and Gass: Your Face Left Before You

Buke and Gass is another boy-girl duo from Brooklyn, like a less abrasive Sleigh Bells. "Your Face Left Before You" is noteworthy for its shifting tempos, which divides the song into several mini-suites. The pounding drums are the glue that holds everything together.

Robyn: Hang With Me

Three things Sweden is known for: Blondes, beauty and immaculately made pop music. "Hang With Me" reaches an ABBA level of catchiness and sophistication. The web of happy synthesizers mask the meloncholy of the lyrics. Robyn wants to be just friends, but she sounds tentative, as if she knows it won't work out. In a perfect world, Robyn would be the biggest pop star of them all, but America wants Ke$ha.
