Speaking with a musical vocabulary that inflects the language of post-minimalism with Puerto Rican musical traditions, composer Dan Román is a polyglot. His work connects at the roots through rhythm: obsessive ostinatos, juxtaposed patterns that create evolving permutations, the hypnotic character of a steady pulse. Música de Palladium, his innova debut, is peppered with quotes from songs and dances from these traditions, mingled with counterpoint, shifting metrics and poly-chords. Mr. Román teaches composition, music theory and electronic music at Trinity College, Hartford, CT.
