Harberg's PRAYER is a rarity in the modern concert repertoire, beautiful romanticism built of a haunting aria for solo tuba. Within the reach of younger players, PRAYER has been championed by top professionals for its expressive and dramatic power and aura. The acclaim for this work has led to versions for orchestra, for a variety of other solo instruments with piano, and to the slow movement of Harberg's Concerto for Viola and Orchestra.
