The superb flute, harp, viola trio, Hat Trick, returns to Bridge with a fascinating program of recent works coupled with a classic. The trio, April Clayton, flute; Kristi Shade, harp; and David Wallace, viola, perform new music by Thea Musgrave, Daniel Dorff, Jessica Meyer, David Bruce, and Angelica Negron alongside Sir Arnold Bax's 1916 "Elegiac Trio".
