I've never been a big fan of his recordings, I mean they're not terrible, just kind of... "stodgy" ?
I heard him live in 1981 or 82, he played Beethoven's op.10 #3, op.109, Debussy's Estampes and Liszt's Dante Sonata. Extraordinary concert! I've rarely heard a tone like that, and what projection; I've never heard anyone more alive, and so involved with and committed to what they were playing. I think he was one of the pianists who had to be heard live; I think piano was easy for him, and maybe without the stimulus of the live audience, in the studio he just cranked it out; he needed the people there to really express himself, or maybe it just doesn't come through the recordings. People who heard Rubinstein say much the same thing, "oh his records are wonderful, but when I heard him live!"......wish I had.....
