The CD's booklet in a recording of this Puerto Rican's chamber works don't reflect those on the CD. It's 'Piezas Caracteristicas,' CRI 724: clarinet-based works. Cover and booklet both say there are 5 tracks, one per composition, yet my player reads 19 tracks. I could figure out which tracks correspond to each work, given the instrumentation, yet wonder about movement names as well. Can you help? Incidentally, Sierra (b 1953), who worked with Ligeti and teaches at Cornell, is highly recommended. He's got an impressive cello concerto on the Mexican label Urtext, as well as the gem piece, a piano trio, on an anthology called 'Voces Americanas: Voices of Change' (with other wks by Davidovsky, Lavista, Leon, and RX Rodriguez). That's on CRI 773. Anyway, if you have Sierra's 'Piezas Caracteristicas' CD, and know more than I do about its contents, can you lend a hand? Thanks in advance. Bert Bailey
