The emotional intensity of Romanticism marries disciplined technique in the music of Hannah Lash. “There is a high seriousness to Hannah,” says Martin Bresnick, her mentor at the Yale School of Music. “It’s almost Puritan—it’s a single and direct expression of one’s soul. It’s a very American type, and she burns with it.” An accomplished harpist, Lash will play her own work alongside the JACK Quartet. The night also includes two world premieres, one of them a new piece for a surprising chamber group: trumpet, trombone, bass clarinet, and baritone voice.
