A keynote address I delivered in 2012 for the Nancarrow festival in London is going into Music Theory Online, the web journal of the Society for Music Theory. The above link [updated 3.25.14] was put up for my proof-reading convenience, and I don’t know how long it will remain before being whisked behind some paywall or something [it won't be]. But it explicitly states that I own the copyright, so for now knock yourselves out. Readers of my Nancarrow book will not find anything particularly new here, though I do talk more, I think, about Nancarrow’s place in American music in general than I have elsewhere. But the prize is at the end: an mp3 of Nancarrow’s piano roll RR, one of his most elaborate finished works that isn’t one of the canonical (and I don’t mean canonic, I wish my students could grasp the difference) player piano studies.
