Flutist Jeffrey Cohan arrived in Chicago just three years ago, but he’s already made enough friends among local musicians to launch this summer’s Hyde Park Chamber Music Festival. The festival’s half a dozen concerts in three weeks promise a modest, informal atmosphere and plenty of variety to please players and listeners alike. This inaugural recital features Cohan, clarinetist Dileep Gangolli (another newcomer and a PhD student at Northwestern), and ace soprano Patrice Michaels Bedi in a bountiful program of mostly 1920s French and American chamber pieces. Cohan and Gangolli will team up to play Villa-Lobos’s Choros no. 2 and Jazz Set by William O. Smith, Dave Brubeck’s clarinetist sidekick. The characteristically suave Gallic songs of Ibert, Roussel, and Andre Caplet will feature the soprano and flute, and modern English vocal writing for soprano and clarient will be represented by the lyrical and tradition-minded songs of Gordon Jacob (based on medieval madrigals) and Vaughan Williams. All three musicians will perform Copland’s As It Fell Upon a Day, and as a bonus Cohan and Michaels Bedi will freely improvise on short verses from the great indian poet Rabindranath Tagore’s Fireflies Thursday, 8 PM, Augustana Lutheran Church of Hyde Park, 5500 S. Woodlawn; 363-3753.
