The object is a mysterious thing. I'm intimately familiar with Part's Tabula Rasa, which this book re-presents in its original recording, along with the original liner notes and photos; in terms of what's new to me, there's also a new short introductory note, a Part discography, and - the main event - 'autograph' manuscript copies of the Cantus and "Tabula Rasa" itself, and scores for all four of its pieces. Not being especially musically literate - which didn't stop me, a few years back, from tracking down and buying a copy of the score of the piano/violin "Fratres" - the scores don't mean a lot to me, but when I saw this in Readings yesterday, I knew that I wanted to own it anyway. Call it the aura, or something.
