It has been a long while since a major pianist planned to play Beethoven 32 Sonatas in Paris – I remember the series of concerts given by Alfred Brendel and Maurizio Pollini in Pleyel, but that was in the 90s!
The 2nd concert played by Barenboim at the Philharmonie covered a large scope, with 4 Sonatas from different periods. Some artists prefer to play the works chronologically, others prefer to select pieces as they see fit, and both choices have their charm.
