Surprisingly, da Backhoe's timing of da 10/2 stood unchallenged until you know what.
In any case, get RUDY's set as soon as itz released. it comes wit a bonus e minor concerto on da same disc. 
Yep, no doubt his 2nd is absolutely superb. I just wish he was as good of a musician.
Speaking of selected etudes I still think that there is nothing more beautiful and accomplished in term of musicality and unhuman velocity than Ignaz Friedman's op.10 no.7 etude. His op.10 no.12 is breathtaking, as well. Anybody heard M. Argerich op.10 no.4 from Chopin competition?
One of my favorite sets is Grigory Ginsburg (unfortunately only op. 25). By modern competition standards he plays them slower , but very beatiful. He got into studio, played them all, and left even without listening back, as everything he was recording.
In Ashkenazi's first recording (he was 18 then, I think) some etudes are pretty fast and kinda stupid.
I heard live G. Sokolov with Op.25 set (it was released from the same concert). In the hall it was absolutely stunning--even more impressive than in the recording. Mind you, in the first half he played Hammerklavier.
Also, ones I heard him playing No.23 as an encore. The only thing I can remember, was the first E, then all my body got as deep into seat as it could, as if somebody put on my shoulders many ton weight, and the next, when it was all over, found myself (as all the audience) jumping from the seat, yelling like crazy and stamping with feet.
Oh yeah, probably reason for flames, but I could not stop laughing listening to Sziffra's set.
