The fourth volume of the complete recording of all 18 piano sonatas by W.A. Mozart - Mozart, the traveling whirlwind - includes the sonata movements in G minor, KV 15p and Siciliano in D minor, KV 15u from the London sketchbook of the 8-year-old Mozart, the sonata movement in B flat major, KV 400 / 372, and sonatas nos. 7, 8, 9. Michael Wessel combines the insights of historically informed performance practice with the rich, colorful tone of the modern Bosendorfer concert grand piano in a refreshing way: a lively, contrasting mixture of speaking and singing characters.
