Raymond Bisha presents an overview of works written by Beethoven during his middle years period. It’s a companion resource to the latest release in Naxos’ monthly digital album series featuring the music of Beethoven in this 250th anniversary year of his birth. February’s compilation album (9.30206) presents a programme of works written between 1802 and 1815, those dates marked respectively by performances of his ‘Kreutzer’ Violin Sonata and his Fourth Cello Sonata by major Naxos artists violinist Takako Nishizaki and cellist Maria Kliegel. Fine examples of his choral, chamber, concerto and symphonic works make up the rest of this attractive compilation.
