I heard many great performances of Mozart's Piano Sonatas including: Uchida, Arrau, Wurtz, Eschenbach, Horowitz, and Kempff to name few. But Gulda's tone and interpretation is exceptionally unique, he plays Mozart with full involvement, dedication, passion and inspiration I've never heard from any other player. Those tapes shed the light on a great artist at his most intimate moment of work, as those tapes were supposed to be personal and not intended for public, and hence the sound quality is not top notch but it's worth it considering the legendary performance.
Johann Friedrich Fasch (1688-1758) was a forward-looking musician who, though a contemporary of Bach, anticipated Haydn and Mozart in the classical style of his compositions. In his younger years he held several positions before he became the music director for the chapel at the court in Zerbst, where he remained for 36 years. He also enjoyed a close connection with Dresden musicians, chiefly with the concertmaster of the Dresden court orchestra, Pisendel. These works are thought to have been some of Fasch's many compositions for the famous orchestra at Dresden.
Two of these are three-movement works called overtures; these represent a kind of "overture symphony" that Fasch created himself. Two string symphonies and two concertos are included also, the concertos showing the influence of Vivaldi, whom Fasch admired. With the exception of one symphony, which has four movements, every work here has three.(Ardella Crawford)
