More films about music: br Every year, crowds from around the world flock to the small Serbian town of Guca, for its famous, annual trumpet festival. The lively, upbeat music makes for a great 5-day summer event and gives less-known bands a chance to practice, get noticed and make it big. But behind the fun and carefree festive atmosphere, few people see the gruelling demands placed on the musicians dedicated to their art. Premieres on 28 November.
