The Gramophone Award-winning pianist Kirill Gerstein has recorded Rachmaninov's Second Piano Concerto with the Berliner Philharmoniker and Kirill Petrenko: it forms part of a twinned release, 'Rachmaninoff 150', from Platoon. James Jolly met up with Gerstein a couple of months ago in London to talk about playing the music of a composer who left us two recordings of the concerto as well as being one of the greatest pianists ever to have lived. The second part of the programme includes solo works, with the Corelli Variations forming the centrepiece.
