The Wall Street Journal hails Grammy Award-winning violinist Jennifer Koh as “a musician of immaculate control, keen intelligence and a slightly cool demeanor.” Listeners at Dartmouth College’s Rollins Chapel in Hanover, N.H., can observe that commanding style at Koh’s “Bach and Beyond” concert — also showcasing works by American composers Philip Glass and Missy Mazzoli. With more accolades than you can shake a stick at, including Musical America’s 2016 Instrumentalist of the Year, Koh pulls audience members into her forward-thinking string ethos through modern interpretations of classical compositions — and expands the contemporary violin repertoire by playing new works written specifically for her.
