The prize-winning Arditti String Quartet, known internationally as celebrated interpreters of contemporary and 20th-century music, will perform at the University at Buffalo on March 20 as part of the March concert program presented by the Department of Music. The concert schedule also will feature faculty recitals by pianists Stephen and Frieda Manes, and the Bugallo/Golove/Nelson Trio, whose members are strong proponents of new music, as well as a production by the UB Opera Workshop of Henry Purcell's "Dido and Aeneas."
