It was a nice event, in an early 19th century Masonic hall in the city of Frankfurt, only 150 seats, good acoustics. Nice moderation explaining the music, some anecdotes from their concert life . I have been following them for those many years, have most of their numerous recordings, they are all my generation, we have grown old. Their performances have reached a stage of cool wisdom and relaxation without losing any of the energy the music needs. Great.
