With both European bona fides (that Watson fellowship with Nadia Boulanger in Paris) and studies with composers that can sound European (those PhD lessons with Leon Kirchner at Harvard), American composer Robert Sirota remains precisely that: a quintessentially American composer. In his mature works, thorny chromaticism often plays nicely within rounded, deliberate forms. And there's always a true economy of means -- no motive where none intended. European-inspired, maybe, but his is a curious blend, no doubt informed by Sirota's many academic appointments up and down America's eastern seaboard (NYU, BU, Peabody, Manhattan School of Music). Not that Robert Sirota is an ivory tower, himself. Case in point: Sirota's brand new, beguiling work for Sandbox Percussion, Spindrift.
