Still in his twenties, French violinist Théotime Langlois de Swarte combines supple athleticism with precocious musical intelligence. He makes a much-anticipated Proms debut as soloist with his ensemble Le Consort in a programme built around violin concertos by Vivaldi and the repertoire that first lit the touchpaper for the talented young musician as a teenager. The programme also includes works by Legrenzi, Marcello and Matteis Jr.
