Completed in 2008, Michael Hersch's 2-hour work for horn and cello, Last Autumn, has been described by the Philadelphia Inquirer as a "portrait of something too huge and undefinable, glorious and terrible, to be seen in anything more than glimpses." A work "whose riches defy the harmonic limitations of the instruments. ... Together, they created wild portraits of alienated togetherness."

Performed here by hornist Jamie Hersch and cellist Daniel Gaisford, for whom the piece was written, Last Autumn is the second in a series of evening-length works written by the composer over the past decade.
