In the sleeve notes Part writes about his music being 'white' so that the listener can bring his own 'colours' to it. Exactly. The three versions of spiegel im spiegel are almost transcendental and they are very difficult to get out of your head after you've listened to them, and even then never completely. Norman Lebrecht, in the latest edition of his book on 20th century music, is so dismissive of the piece that one wonders if the man had his wits about him when he was listening to it. I do not understand why there aren't more opportunities to hear Part's stuff live. I once had the unexpected pleasure of hearing, at Southampton University's Turner Sims, a small string ensemble perform a piece which I had only previously heard with piano and violin. To hear a piece one knows and loves played ever so slightly differently is quite something, as this record perfectly demonstrates.
