Based on the amphitheater in the ancient Greek city of Epidaurus, and nestled in a natural valley, the Waldbuhne theater seats 22,000 in leafy comfort and remains one of Berlin"s favorite open air concert venues, with magnificent views of the stage. World class conductors lead the Berlin Philharmonic in evening concerts of popular Italian, French, Russian and American favorites. Who better to conduct an evening of evocative tango and Latin American inspired rhythms than Argentinean-born Barenboim? Despite playing music outside their usual repertoire, the Berlin Philharmonic enthralls the audience with an exotic program, which begins with Ravel"s Bolero and Bizet"s Carmen Suite and then features special arrangements of lesser known melodies and dances from a host of South American composers.
