I heard both discs for the 1st time & really liked them both right away but what really stood out were the Eroica Variations. Apparently they were obscure, weird pieces that nobody ever listened to or recorded until Gould recorded them. The 2nd variation is pretty unbelievable, I've never heard anyone play so fast. It's not just fast though, it sounds good too, loud & incredibly dramatic, tense & emotional. I'd put these Eroica up there with Bach's Goldberg Variations in my collection. I agree 100% with the other reviewers.
