Formed in Frankfurt 15 years ago and now based in the North Sea port city of Bremen, the Deutsche Kammerphilharmonie is a self-governing, largely self-supporting ensemble well on its way to fulfilling its promise of unorthodox collaborations; the youthful multiethnic orchestra of 30 players has performed with the Kronos Quartet, John McLaughlin, and the Art Ensemble of Chicago, among others. When the group visited Chicago in the winter of 1991, backing up violinist Gidon Kremer, local reviewers noted the aggressiveness and cohesion of its playing. These qualities–along with uncommon lucidity and precision–are even more prominent on the DK’s latest CDs on Berlin Classics, which include early Beethoven symphonies and works by the Soviet maverick Sofia Gubaidulina. This augurs well for the orchestra’s Ravinia Festival debut, a collaboration with violinist Jaime Laredo and 28-year-old Barcelonan flamenco vocalist Ginesa Ortega. Laredo will serve as both soloist and conductor for Mozart’s Third Violin Concerto, and he’ll lead the DK in Grieg’s Mozart-wannabe charmer the Holberg Suite. The showstopper, however, should be a rare revival of Manuel de Falla’s original 1915 version of El amor brujo. Based on an Andalusian Gypsy tale, this ballet score is an enticing brew of spiky rhythms and colorful effects on which Falla’s reputation securely rests. Monday, 8 PM, Martin Theatre, Ravinia Festival, Green Bay and Lake Cook Rds., Highland Park; 728-4642.
