This is an excellent and varied selection of composers from the very well known like Palestrina, Monteverdi, Bach and Vivaldi, through the less famous but familiar like Frescobaldi, Sainte-Colombe and Zelenka, to the downright obscure. It is all delightful: the musicians are uniformly excellent, and include such great names as Gustav Leonhardt, Cantus Colln, Christopher Hogwood and so on. They give fine performances both of the familiar works and of the less familiar ones. Obviously there will be discs you like more than others and you may already have favourite versions of some works, but these discs are never less than very good and are often outstanding.

It won't do to claim the cello concertos of Leonardo Leo (1694-1744) as unknown masterpieces. But if you enjoy hearing a composer struggle with musical materials in an era of transition (might be relevant to today's scene, eh?), you'll find these interesting. Leo was posthumously praised by both Charles Burney and E.T.A. Hoffmann, but today he is known vaguely, if at all, as one of the forerunners of Classical-era opera.

It was in Amsterdam in 1740 that a lawyer named Hubert Le Blanc published an astounding work that defended the use of the bass viol at a time when the violin and the cello were becoming more and more important in Parisian musical life. This recording provides a musical equivalent of his essay, depicting the initial success of the bass viol and of Monsieur de Sainte-Colombe (celebrated in the film Tous les matins du monde), its moments of glory and, above all else, the repertoire of the viol, violin and cello during the first half of the 18th century.

Why is it that cellists who bemoan their lack of concerto repertory continue to neglect CPE Bach's three essays in the genre? It's a mystery; they're excellent pieces, full of infectious nervous energy in their outer movements and tender lyricism in central ones. They aren't unknown to the recording catalogues, however, not least because they also exist in alternative versions which the composer made for flute and harpsichord.
