A split CD of works by Noah Creshevsky (4 tracks) and If, Bwana (3 tracks). While on the face of it this may seem a somewhat odd pairing, the pieces recorded here comment on and highlight each other. And an aural adventure is indeed in the offing. Trained in composition by Nadia Boulanger in Paris and Luciano Berio at Juilliard, Noah Creshevsky has taught at Juilliard, Princeton University, and Brooklyn College. He was director of the Center For Computer Music (1994-2000) and is currently Professor Emeritus at Brooklyn College of the City University of New York. His musical vocabulary consists largely of familiar bits of words, songs, and instrumental music that are edited but rarely subjected to electronic processing. The result is a music that obscures the boundaries of real and imaginary ensembles though the fusion of opposites: music and noise, comprehensible and incomprehensible vocal sources, human and superhuman vocal and instrumental capacities. Creshevsky's most recent hyperrealist compositions explore the fragmentation and reconstruction of pre-existing music in combination with original synthetic and acoustic materials. Moments suggest musical environments of indeterminate ethnicity --simultaneously Western and non-Western, ancient and modern, familiar and unfamiliar. Hyperrealism is an electroacoustic musical language constructed from sounds that are recognizable parts of our shared environment ('realism'), handled in ways that are exaggerated or excessive ('hyper'). Al Margolis has been working under the musical pseudonym If, Bwana since New Year's Day 1984.
