Mozart:
Concerto I after Sonata Op. V, nr. 2
Concerto II after Soanta Op. V, nr. 3
Concerto III after Sonata Op. V, nr. 4

Bach:
Sonata I, V and VI

Johann Christian Bach was one of the very few contemporary composers whom Mozart sincerely appreciated, even revered. His Sonatas Op. 5, published in 1766, apparently appealed to Mozart so much that he reworked three of them into harpsichord concertos a few years later. Inés Moreno Uncilla presents these sonatas op. 5, taking into account Mozart's arrangements of sonatas 2-4.
