On Saturday the children played at the Carioca Culture Centre in Rio city centre alongside the drumming group Balança mas Não Cai. It was the first time they had played outside the favela.
The trombone player is 18 year-old British musician Rowena Smith, who is living in the favela and teaching the children on a voluntary basis for the next six weeks.
Welcome to the project, Rowena!
