Twin brothers Joseph and Erik Duemig, the co-founders of Chicago-based indie-folk band The Window Theatre, are throwing a release party for their new EP, "Away" at Subterranean on December 11th. What’s more, the twins will be celebrating their 21st birthday on stage when the clock strikes midnight. To celebrate, they will be giving away a free copy of their new EP to the first 50 people through the door, and a compilation of new music from all the bands playing the night (The Window Theatre, Carbon Tigers, Katz Company, and Late in the Playoffs) to everyone in attendance. The EP was recorded in the twins’ hometown of Austin, TX. They played every instrument on the record except for drums, which were provided by the twins’ friend and the album’s producer, Austin singer-songwriter Danny Malone. Show at 10:00 PM. Cover is $10.
