Mission is Launched

Aren't they cute.

Here is a description of the launch of Cecilia Bartoli's Mission concert series in Munich yesterday at Schloss Schleißheim .  The interesting part comes at the end where the reviewer describes a kind of Baroque jam session between Bartoli and a trumpeter.  That would be something to hear.  The concert ended with a duet with Philippe Jaroussky.  I've heard a bit of their duets together, and they are a joy.

Apparently there were fireworks at this concert. I can't stop laughing.  How do they get them to go off in rhythm with the music?
