The Rochester Philharmonic Orchestra starts off its 90th season with the bang from a sergeant's gun: Sgt. Pepper, that is. Joined by the Classical Mystery Tour, a group that will be performing in tribute to the 45th anniversary of The Beatles' "Sgt. Pepper's Lonely Hearts Club Band" album, the RPO will also be starting the season off in style with its red carpet spectacular dinner and carpet walk, as well as a post-concert party for ticket holders. Beatles costumes are optional (but we know you still have those Technicolor coattails ready anyways).
