This sequence of photographs shows the rehearsal in the Great Hall at Dartington in the summer of 1996 for the performance and recording of Lou Harrison’s Piano Concerto by Joanna MacGregor. With him are his composition students from that year, who included the Irish composer Ciarán Maher. In the background can be seen music critic, musicologist and composer Wilfrid Mellers. Joanna MacGregor’s performance was recorded in 1999 in Sydney. The Sydney Symphony Orchestra was conducted by another regular Summer School visitor, Sian Edwards .
