The metro area's freshest entourage of experimental musicians go back to their roots with some avant-garde classics of the 20th century: George Crumb's Vox Balaenae and the underperformed pop-minimalist piece Stay On It, by the late Julius Eastman. Also on the program, works by Tom Johnson, Mary Jane Leach, and some Tears for Fears (why not?) Get advanced dicount tickets at http://www.brownpapertickets.com/event/53752
