An evergreen masterpiece, an under-appreciated jewel and a great 'what might have been' - pianist Mark Bebbington and the Royal Philharmonic Orchestra conducted by Jan Latham Koenig explore the personal and musical connections between Edvard Grieg and Frederick Delius. Heard together on an album for the first time, the Piano Concertos by Grieg and Delius reveal the full extent of the composers' friendship and mutual admiration. Composed in 1868, Grieg's Piano Concerto in A minor has become one of the cornerstones of the repertoire. It's famous opening timpani roll heralds a ravishing display of virtuosity lit up by the melting melody at the heart of an immediately recognizable masterpiece. Also in a minor key, Delius's C minor Piano Concerto was inspired by a performance of Grieg's Concerto in London in 1888. Grieg's gifting of a copy of the score to Delius spurred him on to write his own Concerto. A first draft in 1897 was followed by two further revisions over the next decade before the final version heard here in a rare appearance. Grieg's mooted Second Piano Concerto was never completed, but the 150 bars he did sketch hint at what might have been. Robert Matthew-Walker has fashioned the existing material - in various stages of completion and detail - into a coherent single movement to give, for the very first time, the clearest indication of what Grieg had in mind for a work left tantalizingly unfinished. Both this and the solo piano version - also arranged by Robert Matthew-Walker - receive their premiere recordings here.
