The seven siblings of the Kanneh-Mason family - Konya, Jeneba, Sheku, Braimah, Aminata, Mariatu, Isata - play classical music together, and now they've recorded their first album as a family, 'Carnival', which will be released by their record label Decca on 6 November. Written by French composer Camille Saint-Saëns, the musical suite of movements is dedicated to animals including lions, elephants and fish, because "we feel there should be more classical music aimed at children", as Isata says to the BBC.
