Why did the adventurous orchestra Eos fold after 10 years? Conductor Jonathan Sheffer ponders the question: “Ironically, Eos’s decline during the past year happened against the backdrop of the rise of Red {an orchestra} in Cleveland, now entering its fourth season. The opposite trajectory of these two groups perfectly manifested all that was problematic with Eos, and all that is right with Red. With only my programming ideas in common, Red and Eos, each in its own way, embody all the challenges and rewards facing the smaller, more iconoclastic arts groups in America.”
