i uploaded this... listen to the chords about 3/4 the way through this... where he goes in and out... stunning... and yes they are chords, not octaves... on the score it says "as fast and loud as possible"!Also, about 7 mins into the movement is even more furious octaves... but buy the dvd for them!Tom
There's something about the way Horowitz plays virtuoso stuff, though, isn't there? Even when he might not be the fastest (by the metronome) he gives it a pizzazz which for my money has never been excelled.
