Monteverdi 450 — the Monteverdi Choir and English Baroque Soloists’ tour of his three operas to 33 cities across two continents — began with his penultimate work Il ritorno d’Ulisse in patria, at Bristol’s Colston Hall. It was a marvellous occasion, uplifting and entertaining. I hadn’t been to the Colston Hall before, and was most impressed by its acoustics.
