Had these two on my wishlist for a long time and finally found them online for a good price tonight. The first one has her mono recordings of the complete Partitas from the 1950s. The second one has her 1957 Goldberg Variations, Italian Concerto, French Overture (Partita) in B minor and her 1959 Duets BWV 802-805. I have a ton of volumes from this series and highly recommend them. The performances are always special and are often had to find elsewhere on CD.
