At the time that Beethoven wrote Opus 131 it was considered fiendishly difficult," says violinist Colin Jacobsen of Brooklyn Rider. "When told by the musicians who first played it that it was really difficult, he said 'I'm not writing it for you, I'm writing it for the future." The New York-based quartet, in the final ChamberMusic@Beall concert Sunday, April 7 at 3 pm, may very well emblemize that future. Praised for its “stunningly imaginative” performances (Lucid Culture), the adventurous, intrepid string quartet combines a wildly eclectic repertoire with a gripping performance style that continues to attract legions of fans and draw critical acclaim from classical, world, and rock critics. NPR credits Brooklyn Rider with “recreating the 300-year-old form of string quartet as a vital and creative 21st-century ensemble,” and Vice likens Brooklyn Rider to “motocross daredevils who never screw up a stunt.” At home in both clubs and concert halls, Brooklyn Rider has appeared in venues as varied as New York City’s Joe’s Pub, the San Francisco Jazz Festival, Japan’s Todai-ji, the Library of Congress, and the South By Southwest Festival. Through creative programming and global collaborations, Brooklyn Rider’s “down-to-earth demeanor…demystifies contemporary classical music and invites everyone into the tent" (Time Out New York). Beethoven's Opus 131 is the program's finale and is preceded by Brooklyn Rider's group composition Seven Steps, upon which it was modeled. Like the Beethoven, it's divided into seven movements, but it also suggests the spiritual world that Beethoven explored in his later works—in addition to all of the Biblical references to seven, the Buddha was said to have taken seven steps at birth. The program also includes an original by Rider violinist Colin Jacobson, Bartok's String Quartet No. 2, and "Budget Bulgar" by contemporary composer Ljova Zhurban, a fiery Klezmer tune inspired by Pete Sokolow, the king of Jewish weddings in New York.
