This was curious programming: part choral and orchestral blow-out, part intimate chamber concert. The evening's hosts, the BBC Symphony Orchestra and conductor Leonard Slatkin, began with three of Ravel's deliciously vivid dances, forming a kind of suite with a solid but still sinister account of La Valse as its culmination. Joined by the BBC Symphony Chorus, they closed with the bombast of Honegger's rarely performed Le Roi David.

But in the middle, the orchestra had generously donated a slot to the winners of the Chamber Ensemble prize at this year's Royal Philharmonic Awards. The Nash Ensemble returned the favour by stealing the show. Their superb performance of Fauré's Piano Quartet had everything - wit, tenderness, passion, serious intent and subtlety. Looming large was Lawrence Power's characterful viola-playing, although all four musicians blended with absolute sensitivity. The audience was held rapt.

Subtlety isn't the defining feature of Le Roi David, Honegger's 1921 symphonic psalm based on the life of the Old Testament king. Written for a mostly amateur ensemble, it does have a school-concert feel, with colourful but basically simple orchestral lines and singer-friendly choral numbers, here delivered lustily by the BBCSC.

The story rattles along with only brief pauses - for a rabble-rousing chorus when the Israelites are regrouping, or, more often, for reflective numbers from the vocal soloists. Early on, Slatkin could have been more sensitive to these: the tenor Werner Güra was almost drowned by the orchestra. The work affords few opportunities for the performers to get really stuck in, but the lament for women's voices at the end of the first part was one extended item that came across compellingly. Although most of us will have had to rely on the printed translation to keep up, François Le Roux's authoritative French narration knitted it all together convincingly.
