I love the Hogwood Mozart Requiem, but it’s a curio because he refuses to use any notes that might have the taint of Sussmayr, so it sounds very truncated. I think that is being a bit extreme, since Sussmayr was an accomplished 18th century composer, had been a student of WAM, and was the choice of Frau Mozart to finish it off.
I found digital copies of all the Ristenpart Bach recordings, a 6 CD set from France, via eBay, at about $15 per CD. A bit pricey, but I had bought a turntable and phono pre just so I could play treasured LPs that are unavailable digitally, and a substantial fraction of my lp collection are the aforementioned Ristenpart Bach recordings. I had bought a handful of other Nonesuch and Vox/Turnabout recordings that I now have been able to locate digital versions as well. Considering selling the analog rig as listening to these noisy, poorly pressed records is reminding me of why I got out of vinyl in the first place
