The Hartt School Wind Ensemble presents recent concertante works by three contemporary American composers—demonstrating once more the versatility of the ensemble, heard here in conjunction with soloists. Susan Botti’s sull’ala is inspired by flight, expressed in rhythm, harmony and texture, while Jess Langston Turner describes powerful meteorological phenomena in Heavy Weather. In Guignol, Stephen Michael Gryc conjures witty banter and frenetic action from his puppet hero.
