One of our serious Deli faves Spacin’ is performing a free show tonight at the Institute of Contemporary Art for their FREE FOR ALL series. However, the usually four-piece made up of Jason Killinger (Birds of Maya), Sean Hamilton (Acid Kicks), Paul Sukeena (ex-Spooks), and Eva Killinger has expanded to a nine-piece referred to as the Spacin’ Arkestra. No word exactly about who else will be joining them, except Light Heat’s Quentin Stoltfus on “noisy guitar,” but given Jason’s ties in the Philly indie music scene and his love for early 70s Grateful Dead, I’m expecting some talented players and extended jams filling the Penn building. Institute of Contemporary Art, 118 S. 36th St., 6:30pm, Free, All Ages – Q.D. Tran
