Soler was music master to the princes of Bourbon in El Escorial, the palace of the King of Spain. It’s probable that most of his keyboard sonatas were written for Prince Gabriel and these essentially private works—around 150 have survived—bear comparison with the works of Domenico Scarlatti and C.P.E. Bach. Soler was fond of dance rhythms and guitar imitations, as well as infectious and delightful modulations. These fifteen sonatas are heard here in the order proposed by Rubio’s catalogue. Pianist Martina Filjak—“brilliance, sensitivity and imagination” (New York Times)—is a much admired international artist.
