The world premiere of a specially commission 'encore' piece by the prodigiously gifted American composer Daron Hagen followed [Respighi's
Feste romane] immediately. Titled 'Susurrus,' this deliciously orchestrated four-minute composition was noteworthy for its ethereal delicacy. Imagine the gentlest of ticklings, administered by a feather that is more often anticipated than actually felt.
