A professor at The Juilliard School since 1986, Zyman is one of Mexico’s foremost composers of today. His cello concerto (1990) exhibits solid technique, intense expression, and effective interaction between soloist and orchestra. The author demonstrates much stylistic and formal freedom. His opus mixes both antique and modern references within traditional instrumental usage and prevailing neomodal flair. One outstanding feature is the full exploitation of a basic melody to generate an interrelated musical idiom that reveals both unity and variety. The appendix contains an interview with the Mexican artist.
