In 2012, Austin's soundtrack for the hit PlayStation3 game Journey became the first-ever Grammy-nominated videogame score, also winning two British Academy Awards, a DICE Award, a Spike TV VGA, and IGN’s “Overall Music of the Year”, along with five Game Audio Network Guild awards. Excerpts from the score have been performed all over the world since its release, including by the National Symphony, San Francisco Symphony, Colorado Symphony, Melbourne Symphony, and Pacific Symphony. Austin’s score for the earlier game flOw made him the youngest composer ever to receive a British Academy Award nomination and also won him a wide variety of other game industry accolades, including the Game Audio Network Guild’s “Rookie of the Year.” An orchestral version of this music has been performed at the Smithsonian Museum in Washington DC as a part of their Art of Games exhibit and also included in an exhibition on modern art at New York's famed MoMA.
Austin's film scoring career began in 2007 with Captain Abu Raed, winner of the 2008 Sundance Film Festival audience award and shortlisted contender for the 2008 Academy Awards for both Foreign Film and Best Original Score. Following that have been films such as the Sundance hit Grace, The River Why, Standoff, The Rendezvous and Bullet Head. His newest film is The Last Movie Star, directed by Adam Rifkin and starring Burt Reynolds and Ariel Winter.
