Gerstein asserted himself as a top-rank virtuoso early on, with his first flurry of passagework. This was far from empty, brilliant fingerwork, however. The spirit of Bach was in these notes, as the Russian wove Rachmaninov's mercurial toccata through the orchestral sparkle.
When Rachmaninov opens up his big Russian heart, Gerstein held nothing back; in such moments he gave us unabashed, full-on romanticism, with beautifully gauged rubato and dynamic shadings.
Glittering scales seemed to border on glissando gleam and, when full power was called for, Gerstein got just that from the resident Steinway.
An encore was not expected, but a charming left-hand study by Rachmaninov's friend, Felix Blumenfeld, was stylishly rendered with palpable affection.
After interval, the orchestra gave us the most celebrated of all ententes cordiales between French and Russian culture - Ravel's orchestration of Mussorgsky's Pictures at an Exhibition.
Minor mishaps aside, one felt the Gallic sensibilities of the conductor at work here. The eerie hues of Gnomus were perfectly gauged for the hall, while the chattering Limoges marketplace projected the excitement of waiting for the curtain to rise in a Montmartre cabaret.
