I guess the chord one is the one Rachmaninov prefered, I'm not sure if it has a particular name associated with it, maybe someone can clarify that. THere are these 2 different versions, I prefer the chordal one myself, the single one sounds too easy, in comparison.
Rachmaninoff prefered the single note one. He said that the chord one sounded two much like an ending to the concerto, so it would not fit in the concerto. I have the recording where rachmaninoff himself play the 4 concertos, and he plays the single-note one.
Most interesting, but Horowitz, who definitly recorded the best version of this concerto
the best to play for the whole Idea of the COMPLETE concerto is the first one
He didn't "allowed other's to butcher his work".
