Salle: Grosvenor Chapel, Mayfair, Londres

Five hours with five counter tenors: a virtuoso stand-off which impresses, even astounds, but ultimately exhausts even the most dedicated audience by its refusal to cut a single note of what becomes a very long, florid opera by Jommelli. 

Had you been travelling, in the mid 18th century, around the crowned courts of middle Europe, there would have been little debate as to who was the most celebrated opera composer and ensemble: Johann Adolph Hasse and his company at the Saxon court of Dresden.
