The Musical Times In preparing this Urtext edition of Ravel’s piano music, Roger Nichols consulted no fewer than 14 sources - including sound recordings by Ravel himself and other pianists with whom the composer worked. As a result he is uniquely qualified to evaluate the complexity of the sources and, with this edition, has provided today’s pianists with the tools to make their own well-informed performance choices about this infinitely-rewarding repertoire.
