Looking back at this year’s electronic and electroacoustic performances, what is striking is the friendly way acoustic instruments meddled with laptops and other electronic gadgetry, particularly in the mixed concerts by Michael Snow / Alan Licht / Aki Onda, Jason Kahn’s Signal Quintet, and Stevie Wishart / Christof Kurzmann / Werner Dafeldecker. Positive cohabitation seems to be gaining between these two major currents in creative music, all for the benefit of the fans.
