Kenny Chesney: Summer in 3D, a concert film shot in five cities, will hit theaters in April. Chesney is currently editing the film that will be released by Sony Pictures Entertainment's Hot Ticket Division. He got the idea after seeing U2's 1998 film, U2 3D. "It was like something I'd never seen, and I wondered what would happen if we tried to capture some of what was going on like that," he said. The film was shot with 22 3-D camera rigs during concerts in Pittsburgh, Philadelphia, Seattle, Boston and Indianapolis. Chesney is nominated in three categories at the 43rd annual CMA Awards show taking place Wednesday (Nov. 11) in Nashville.
