Pedro Casals, an expert on Manuel Blasco de Nebra, continues his fascinating survey of the Spanish composer’s keyboard sonatas. This, the second in a three-disc series, comprises the final seven sonatas preserved in manuscript in the Montserrat Archive and two late sonatas, the first edition of which is held in the Library of Congress in Washington DC. They show de Nebra’s innovative contribution to the development of the modern piano sonata. Volume 1 is available on Naxos 8.572068.
