The 1957 recordings were issued by EMI in France in a boxed set at a ridiculous (cheap) price, coupled with the Johanna Marzty violin sonatas and partitas.
I have this set and enjoy it (the Martzy Bach is a treasure IMO). However, IIRC, Starker did the Bach suites at least three times, maybe more. The EMI are good but the early-1960s Mercury versions shown by the OP are still my favorite, powerfully projected, gutsy where warranted yet articulate, and very beautifully recorded; I have these on original Mercury AND the Golden Imports pressings AND on CDr from downloads! I also have one LP from the Fournier set, which provides me with an elegant alternative to Starker when I'm in the mood.
I have Casals complete on CD, which I admire but don't really listen to very often. Normally I respond well to Casals' playing, but for some reason I don't feel much involvement in this set. Part of the problem may be the recording. It's not really the age--I'm used to older recordings. But while mine is an early Naxos edition, this is one time when I can't say that their transfers are really preferable to a good earlier vinyl transfer (I used to have the LPs on GPOC library edition, either British or French pressing). It's been a while since I tried Casals, though, so perhaps I should pull it and give another listen. I'm listening as I type to the Starker/Mercury suites 1-3, so that would give me a good basis for comparison.
Other versions? Well, I have Harnoncourt on a cheapie MHS set I picked up, but I've only listened through that set once, so I'm not ready to make pronouncements...though I can't say I was overwhelmed, I'm willing to give him another shot. Yo Yo Ma's I checked out from the library, but I wasn't thrilled with his, either. Maybe my taste in the Bach suites has been formed and doesn't want to be altered!
FWIW,
