Pianist Christopher O’Riley and cellist Matt Haimovitz collaborate to forge a fabulous mash-up that unleashes the lyrical and virtuosic properties of their instruments.  While the first half of the program is pre-arranged, the second half is programmed from the stage, in true iPod form, as works by Piazolla and Stravinsky mingle with covers from Arcade Fire and Radiohead. The Billings Gazette called the performance “sublime interpretations of classical works…followed by jaw-dropping new works massaged into magic.” Pre-Concert Fireside Chat with NEPR Afternoon Classical Music host Walter Carroll at 6:30 p.m. at the University Club. Sponsors: Baystate Health, Health New England, Applewood Retirement Community, NEPR 88.5FM, UMass Hotel and Conference Center, Preview Magazine. Regular ticket prices $40, $30, $15. FC, GCC, STCC and 17 & under, $10. Purchase tickets by calling 413-545-2511 or 800-999-UMAS, or at fineartscenter.com.
