LISTENING TO CAGE, by way of his Thirty Pieces for Five Orchestras, made me think to check out Feldman, so I went to E-Music to download his Coptic Light. Hearing that made me think of my own Nightmusic, so I put it on next. I'd forgotten how nice it sounds.
Googling it I discover it's available from Audiophile, with the Oakland Symphony Youth Orchestra conducted by Kent Nagano — to my knowledge Kent's first recording. (It was released in 1982.)
I wrote the piece forty-one years ago, I suddenly realize, on looking at my account of it over at shere.org. As recorded, it's a bit over 24 minutes long; quiet; mostly consonant.
