There's classical music and there's "classical" music. I find a great deal of Haydn grates on me. Mozart tires me. Beethoven has helped once or twice. But the composers whose music I enjoy the most lived between the late 12th and early 17th centuries. Thanks to performers like the Dufay Collective and Ensemble Gilles Binchois new life has been breathed into what would otherwise have remained dusty tomes, the domain of scholars.
