Summer Concerts in Europe

I'm going to be in Salzburg again this coming August and looking forward to hearing some great concerts. But there are lots of other great music events in Europe in the summer:

• Verona Opera held in a spectacular Roman amphitheater.
• Vienna concerts at the Musikverien, Schönbrunn and other locales
• Verbier Festival in the Swiss Alps
• BBC Proms just to show that there are festivals that do not start with the letter "V" but sadly, the 2020 season doesn't seem to be up yet

Oh, here is the Salzburg Festival schedule.

For our envoi, Martha Argerich playing the Tchaikovsky Piano Concerto No. 1 with Daniel Barenboim conducting the West-Eastern Divan Orchestra at last year's Salzburg Festival,

UPDATE: A commentator suggested adding this one to the list:
