The final concert of the International Contemporary Ensemble's ICE Fest features works by composers under 35 from a half-dozen countries, music that would otherwise likely be performed only in the composer's hometown. ICE gives these young composers what they need most--performances by musicians who know how to play contemporary music. Quark, a piece for three percussionists by Edgar Guzman of Mexico, will receive the lone world premiere, and Toshtuk le kirghiz, a work for piano and percussion by the deft Montreal-based composer Nicolas Gilbert, will have its U.S. premiere. Dai Fujikura, who was born in Japan but studied in England, has a strong ear for timbre and has won a commission from Pierre Boulez; ICE will perform his wistful Edge of Light for clarinet and string trio. Czech composer Ondrej Adamek's Strange Night in Day Light, for chamber orchestra, exhibits the kind of rhythmic play associated with Gyorgy Ligeti; Alexandra Karastoyanova-Hermentin, who was born in Russia, throws fragments back and forth between the violin and cello in her lilting Kastena; and Eka Chabashvili, of Georgia, fashions a moving sound world out of four taped voices in Polyphonic Voices. All of these works show a high degree of aptitude, as well as an attitude that's decidedly not ivory-tower. Cliff Colnot conducts. Free. Saturday, June 5, 8 PM, Columbia College Concert Hall, 1014 S. Michigan; 312-494-2655.
