The thread running through this disc, brainchild of pianist Mei Yi Foo, is that all three works are hiding something behind the notes. The idea promises more intrigue than it delivers, yet the pieces still add up to an enjoyable programme. With trumpeter Philipp Hutter and the pleasingly lean-sounding Britten Sinfonia, Foo makes light work of the Concerto for Piano, Trumpet and Strings, in which Shostakovich, that compulsive player of musical hide and seek, tries different styles for size. Berg’s Chamber Concerto for Piano, Violin and 13 Wind Instruments, featuring violinist Bartosz Woroch, is a less arch but still mischievous piece; a birthday present for Schoenberg, it includes both their names plus that of their Second Viennese schoolmate Webern encoded in the music. Finally, there’s Saint-Saëns’ Carnival of the Animals, portraying not only the titular creatures but also his colleagues in the French music world; Foo and Ashley Wass make a lovely mess of the Pianists movement.
