I confess that Elgar's Concerto is not one of my favorite pieces (possibly due to overexposure at an impressionable age). It just doesn't hang together right, despite all the lovely things it contains.
I do like Anne Gastinel's playing, however. There's something about it (the elegant tone; the lack of "pushiness") that suits chamber music in particular. Her discs with Aimard (especially the Kodaly, Liszt, Janacek) and Guy (Brahms, Beethoven) are very beautiful indeed.
On this new disc, both the Elgar and the Barber benefit from her concertante, "chamber" style. Maybe ears attuned to the somewhat ardent approach of, say, du Pre in the Elgar will find something a little reticent here? But with a fine recording and stylish playing, this is a splendid coupling that provides new insights into a well known piece (and an introduction to a not very well known piece).
Cool packaging as always from Naïve. A great record company!
