Hi Hamster,
I am a baroque cellist and viola da gamba player, so I am glad to know you are looking into 'performance practice' or 'period' recordings. Have you listened to Andrew Manze, John Holloway, and Rachel Podger? For some reason, British players seem to lead, at least in European recording labels. I am not sure Elizabeth Walffisch has a recording of the Bach partitas, but her playing is also very good. Or perhaps an Italian player like Giuliano Carmignola? I think he is both a modern and baroque player.
In any case, I would be interested to know if you already had these recordings, or what you think about them.
Happy listening!
