Since 1994, SFCA has presented more than 10 works by Kelley, who sang with the ensemble for 5 years. His choral works and arrangements—which have also been performed by Yale University and many Bay Area choral ensembles such as Clerestory, the Grace Cathedral Choir of Men and Boys, and The Choral Project—are notable for their soaring melodies, lush harmonies, and distinctively American sound.
