Bilson is known for his series of recordings (on the Archiv label) of the piano concertos of Mozart, in collaboration with John Eliot Gardiner and the English Baroque Soloists. He has also recorded the complete Mozart piano sonatas for Hungariton. In collaboration with six of his former students Bilson has produced a complete recording, on Claves Records, of the piano sonatas of Beethoven. These recordings use a set of nine restored or replica pianos, each of a type contemporaneous with the sonata being performed.
