The recent Tafelmusik programme - "House of the Devil" - covering Italian Baroque from the early days until the transition to the Classical period was one of its best this year. I especially enjoyed the simple early pieces.
(and yes, there is more to Italian Baroque than Vivaldi, Monteverdi and Corelli.)
The programme did include a Vivaldi horn concerto - but was predominately focussed on less well-known composers. Highlights included:
Biagio Marini - Sonata in ecco for 3 violins and continuo
Giovanni Bertoli - Sonata for dulcian and continuo (The dulcian is an obscure wind instrument)
Tomaso Albinoni - Concerto for two oboes
