When the Portland Symphony Orchestra sent out a press release about two upcoming shows featuring music created by three composers from Mexico, one line jumped out. "The concerts open with [Enrico] Chapela’s lively and suspenseful 'Rotor,'" the release said, "A reflection on his early days playing as a musician in a death metal band." Trust me, gentle reader—this is NOT a description typically found in promotional copy from the PSO. Chapela, as you may have guessed, fits nobody’s stereotype of a stuffy classical composer.
