Pianists David and Hyun Ju Curtin of Lock Haven University will open this year’s Roche Guest Artist Series with a recital of music for four hands, including military marches by Franz Schubert and waltzes and Hungarian dances by Johannes Brahms. They’ll perform Monday, Sept. 10, at 8 p.m. in Walker Recital Hall at Mercyhurst University. The artists will also present a masterclass for students of the D’Angelo Department of Music on Tuesday, Sept. 11, at 12:45 p.m. in Walker Recital Hall. Both the recital and the masterclass are free and open to the public. Since its founding in 1988, the Roche Guest Artist Series has introduced local audiences to a unique mix of acclaimed traditional soloists and chamber ensembles, along with specialized performers in the areas of contemporary music, jazz, Renaissance, Baroque and world music. The Roche events are free and open to the public through the generosity of the Terry and Margaret M. Roche Family. For information, contact Victoria McIlvain at 814-824-2394.
