Gabriel Kahane's Heirloom features a concerto for piano and chamber orchestra by the same name, written by the composer/singer/songwriter for his father, the conductor and pianist Jeffrey Kahane. The Brooklyn-based orchestral collective The Knights also perform on the record. "Heirloom is an aural family scrapbook," Gabriel Kahane says, "exploring, in its three movements, a series of inheritances." The album also features “Where are the Arms,” the title track from Kahane’s sophomore LP, in a new orchestral arrangement performed by the composer (vocals, guitar, electronics) with the Knights.
