Organized by Gene Coleman, this concert represents the combination of two programmatic strands that Coleman has been working on intensely for the past several years. One category,”Eurethos,” has identified the ongoing influence of European aesthetics on American culture. And the second, “Transonic,” has featured cross-cultural programs involving East Asian traditions. The result is a bill going under the title Orpheus in China, with Seth Josel (guitar), Hong Wang (Erhu), Carmel Raz (violin), and regulars from Ensemble Noamnesia played music by Richard Barrett, Peter Ablinger, Chao- Ming Tung and others.
