George S. Clinton, chairman of the film scoring department at Berklee College of Music,is appearing this weekend at the Chattanooga International Film Music Festival, where he’ll be performing selections from his “Austin Powers” film scores. Clinton is a Chattanooga native, and as excited as he is to return to his hometown, the composer has also felt at home in Boston for the past two years. “I had been here before, visiting Berklee as a composer, and every time I came here, I loved the city and history,” said Clinton. “It’s been a city for so long and just has being a city down.” Before coming to Berklee, Clinton composed scores for film and television including “The Tooth Fairy,” starring Dwayne Johnson, “The Astronaut’s Wife,” with Johnny Depp and Charlize Theron, and HBO Films’ “Bury My Heart at Wounded Knee,” for which Clinton was nominated for an Emmy. “My favorite scores of my own are when I am allowed to be the most creative — when I’m being handed a blank page rather than a blueprint,” he said. Clinton will headline the festival alongside Oscar-nominated composer Alan Silvestri, who has composed music for “Forrest Gump,” “Cast Away,” “Back to the Future,” and more recently, “The Avengers.” In light of Sunday’s Academy Awards, Clinton said his vote for original score goes to “Gravity,” composed by Steven Price.
