Matt and Kim, Beirut at Pitchfork Music Festival

Here's an unlikely duo from today's performances at Pitchfork Music Festival: Brooklyn's hyper-kinetic Matt and Kim battling for attention with the dreamy melancholy of New York's Beirut.

Beirut -- masterminded by Zachary Condon -- played with presence on the Pitchfork stage, eschewing confidence with its brass trumpets and tubas, mandolin strings and accordion keys. Barely into his mid-twenties, Condon acted like a veteran on the stage, although he did admit that the audience was the largest in front of which his mandolin had likely ever performed.

Meanwhile, on the smallest of the three stages, Matt and Kim pounded out their dance rhythms and melody, all while wearing those perma-smiles their fans have come accustomed to seeing. They too, owned the stage on which they performed. Matt owned up to making a few mistakes in Chicago in the past and dedicated their song, "Yeah Yeah," although written a few years ago, to the summer of 2009.
