Now in its ninth year, Darmstadt's annual birthday concert has become a time-honored tradition. Terry Riley's 1964 masterwork is performed by new music legends including Joan La Barbara, Matana Roberts, Elliott Sharp, Joshua Rubin, Conrad Harris, Pauline Kim Harris, and members of So Percussion and Iktus percussion.

"Archway" is a massive outdoor installation by Eli Keszler, presented as part of Make Music New York. Tuned and extended piano wires up to 380 feet long will be stretched around a massive space, overlapping to form sculptural shapes and a mechanically driven, intense harmonic resonance.
