Ernest Chausson's Concert for Piano, Violin and String Quartet is one of the curiosities of the chamber music repertoire. Part piano quartet, part violin sonata and wholly French in the mould of Fauré or Franck, it is a grandiose work in terms of gesture and running time.

The artistic director of Scottish Ensemble, Jonathan Morton, has arranged the piece for his group; it is an expansion that works rather well, since it gives the strings more weight to counterbalance the demanding, frequently tempestuous piano writing. In fact, pianist Andrew West could even have played out more - his desire not to overwhelm the slow-moving string lines with torrents of notes at times pushed the piano too much into the role of accompanist.

Despite the piece's title, which implies a form of violin concerto, the solo part is predominantly melodic. Some violinists might try to prove otherwise, but Morton, typically, opted for lyricism rather than overt display. Since he assumed the leadership a couple of seasons ago, the ensemble has begun to reflect his playing style: mellow and less driven than that of his predecessor. The resulting sound is less overtly brilliant and glossy, but with more depth and warmth at its core. This was particularly apparent in the ensemble's understated but effective playing of Finzi's tranquil Romance, a piece in which beauty of tone and unforced lyricism are everything.

The ensemble's trademark virtuosic brilliance can still be called on when the music demands. In Walton's Sonata for Strings, the composer's jagged, rhythmic energy came to the fore in the fast movements. In the slow parts, Morton made the most of the Mediterranean-inflected colours, creating a nice link to Chausson's Concert.
