Steins and würstl, dirndls and lederhosen, polkas and schuhplattlers—Oktoberfest in Munich, with the Theresienwiese as Beer Tent Central! This year, the revelry runs from September 21 to October 6, but downtown at the Herkulessaal in the palatial Residenz, Sir Simon Rattle and the Bavarian Radio Symphony might as well be on another planet. Piquant Andalusian airs define Manuel de Falla’s ballet The Three-Cornered Hat, which takes us to intermission. The bookends for the second half are Igor Stravinsky’s Ebony Concerto and Leonard Bernstein’s Prelude, Fugue and Riffs—eight-minute bursts of effervescence commissioned by the big-band leader, clarinetist, and all-around jazz great Woody Herman. In the solo parts, listen for battling licorice sticks from the orchestra’s own Stefan Schilling and Christopher Patrick Corbett, both listed on the roster as first principal clarinet. For the evening’s pièce de résistance, guest artists are in the mix. Extracted from Osvaldo Golijov’s folkloric explosion La Pasión según San Marcos, the nominal concerto for two pianos and orchestra Nazareno adds up to a whopping half-hour’s worth of music. But Gonzalo Grau, who did the extracting, has woven an unconventional texture, often threading the pianos deep within the orchestra fabric even as members of the orchestra take flight in brilliant solos. Depend on the Labèque sisters Katia and Marielle, preeminent among piano duos for decades, to navigate with their signature panache. —Matthew Gurewitsch
