Charangas Delirantes: The idea of the piece is a fictional perambulation through the varied and contrasting sound colours and rhythmic world of dancing, applying to these aspects a distorted perspective as a means for possible discovery. Most sounds are derived from sampled and processed piano music materials by Haydn and Chopin. Additional sounds such as brass, percussion and certain piano colours were created by the composer. Charangas are popular dance ensembles in Hispanoamerica, particularly in the Caribbean.
Cronicas de Ultrasuelio (1992) is inspired by the poetic musicality, irrealism and polylyricism of the unique Catalan and major Hispanic writer J.V. Foix (1894-1987). This piece is for clarinet and electronics. It is an adaptation of a piece for oboe and keyboard-controlled FM digital synthetizers. Commissioned by Urugayan Leon Biriotti in 1992 with the financial assistance of the Canada Council for the Arts. The piece was awarded at the 1994 Helsinki International Rostrum of Electroacoustic Music.
