For the Debussy, I don’t think anyone has yet mentioned the Alban Berg - to my taste by far the best. I’ve heard quite a few versions, and my preference is generally toward the more dramatic, as opposed to a less inflected performance.
I just listened to the first movement of seven performances: the Capet, Galimir, Vlach, Lener, Loewenguth, Jerusalem, and Berg.
The first movement is marked “Animé et très decidé” and the Berg is the most emphatic and dramatic, closely followed by the Loewenguth which I hadn’t heard before. The Galimir was also good, as was the Vlach.
Most disappointing was the Capet - I realze they were associated with the composer, but their version didn’t seem well characterized - the Berg was much more dramatic.
The Galimir is available in a 99 cent Bach Guild box for those not allergic to MP3, along with the Ravel and a lot of unusual works: https://www.amazon.com/Big-Chamber-Music-Box-Vol/dp/B01EIUQ7AO
The Jerusalem has a live version on YT:
The Vlach I have on a Parliament LP.
