I like to recommend the Berliner Philharmoniker under their new and seventh principal conductor in 140 years history: Kirill Petrenko.
As a warm welcome to him and to the public the orchestra played an open-air Beethoven concert infront of Brandenburg Gate - no entry fee.
Fans of classical music might see and hear the recording in rbb Mediathek. Maybe geo-fenced and definitely time-limited available only. It is really worth also seeing him interacting with orchestra and choir - so different to Simon Rattle.
I post it under General Europe because this orchestra is also often playing all over Europe on invitations and events. If you have a chance to attend an event do not miss them.
