Come to the Radius Ensemble concert on Saturday, May 11th, 2013 at 8:00pm in Pickman Hall at the Longy School of Music of Bard College, 27 Garden Street in Harvard Square. This concert features Mozart (String duo in B-flat major, K.424), Morrison (Lonesome Whistle for solo flute), and MIT’s own Harbison (Woodwind Quintet) and Southworth (JAMU for ensemble and Balinese Gamelan World Premiere). When Michael Haydn, younger brother of Franz Joseph, found himself in hot water with the Archbishop of Salzburg for not completing a commission, Wolfgang Amadeus Mozart quickly stepped in as an ally for his friend. He composed two duos for violin and viola, sent them to Haydn, and sanctioned plagiarism by instructing Haydn to include them in the collection as his own. John Harbison’s Wind Quintet is embroidery in sound, “mixtures rather than counterpoints,” to quote the composer. A single strand of melody winnows from a flute in John Howell Morrison’s Lonesome Whistle—exploring the intricate tie between performer and instrument. The concert will close with a world premiere, Christine Southworth’s alchemic Jamu for ensemble and Balinese Gamelan. Student admission is $10; general admission is $20. Buy tickets here.
