“Julia Wolfe has composed a meta myth with »Steel Hammer«: »The work is inspired by my love of legends and the music of the Appalachian Mountains. I fragmented the many different and somewhat contradictory versions of the ballad and wove it into a completely new format. The music often circles around individual words or phrases to tell the ultimate story and its different paths.«

The Appalachian dulcimer (a kind of zither) joins the usual line-up of Bang on a Can with clarinet, a lot of percussion, guitars, piano, cello and double bass and provides for the American country sound. Trio Mediæval, a top-class a-cappella ensemble from Norway, completes the overall sound with its clear soprano and alto voices, which Julia Wolfe particularly appreciates for their great wealth of experience in the vocal tradition of their homeland.”
