Huh, just had a surprising realization: turns out Tetzlaff has recorded Bach's Sonatas and Partitas for Solo Violin three times, and what I thought was his first cycle is really his second and what I thought was his second is really his third. Might not matter too much, only means whenever I've read people talking about them, I had the wrong set in mind lol. "Tetzlaff's second set is my favorite" when they were in fact talking about the other one, etc.

And good to know there's another set of his which I haven't heard yet, his earlies one, so I'll be checking that out soonish
