I'm pretty sure VC was the first guy that improvised using polyrythmns in the way he did. Yes, he got it from Tony and Elvin (and to a certain extent Alphonse M and Jack de Johnette) but the way Vinnie played them (esp on SUAPYG) was highly original and influenced a whole generation.
Also, I think the concept of 'great art has to innovate' is questionable.
When we look back on great pieces of art it is easy to see them as the beginning of a new era when infact they are more like a summation of what has gone before.
