I recently read his book, You And Music (found amongst my grandfather's books). It's written with a strange mix of diffidence and defiance and includes a chronologically-reversed history of western art music which seems most in sympathy with early music and then-new developments in tonality. At one point Darnton marvels at the endurance required to sit through performances of symphonies, a feat he claims unable to understand, although the back-cover bio mentions that he was, at the time, working on a symphony. I'm curious to hear what he came out with, given his stated antipathy for the form. 

Has anyone heard his stuff? How is it? Are there any decent recordings available?
