In terms of electronic music, probably Skrillex because of his sheer enthusiasm.. He has a fantastic energy about him and it's clear that he's always made the music that he wants, and the fact that he's been so successful in that is extremely motivating to me..
In terms of creativity, I look up to people like Pink Floyd, Gorillaz, Godspeed You! Black Emperor, Death Grips, Drake, Mr Carmack, Noisia, Amon Tobin.. The list goes on and on and on.
