I’m working on the first movement of a Kummer Cello duet with my teacher right now (after working on much harder stuff, it’s a relief to play something, well, playable). While searching for a version to listen to, I stumbled upon Magnatune’s humble cello section.
Not too much there, but what you can stream it all online…some nice gems, including this release by Vito Paternoster doing Bach’s Solo Sonatas and Partitas for Violin on cello…quite wonderful. The low range of the cello really makes these pieces sound incredible. You pay what you like for the release – from a measly $5 on up (suggested payment is $8, you cheapskate!).
