Looking up the Gramophone Compact Disc Guide and Catalogue, I see that after only four years of the new medium, there are no fewer than five rival recordings of this coupling. Chief among them are those by the Orlando Quartet (Philips) and the Alban Berg Quartet (EMI). This present account by the Melos Quartet of Stuttgart is among the finest of their records and is not only superbly played but both beautifully and naturally recorded. Intonation and ensemble are perfect, and they are scrupulous in their observance of dynamic markings. So, speaking personally, it would be my preferred version. The slow movement of the Ravel is quite magical.
