Anne Guthrie is an acoustician, composer, and French horn player based in San Francisco, CA. She studied music composition at University of Iowa, and architectural acoustics at Rensselaer Polytechnic Institute. Her music combines processed field recordings and instrumental improvisation while exploiting architectural and psycho-acoustic phenomena to distort and obscure sonic identities. Along with her solo work, she often performs and records with Billy Gomberg as FrauFraulein, and with Gomberg and Richard Kamerman as Delicate Sen.
