Definitely not trying to start an argument, but why would the motivation really matter? For every 1 Ed (or Vai, or Satch, or name your guy...) there are a million others with with massive love for the music and energy those few have created - but no fountain of that creative ‘gift’ where original music came from. For every Mozart there are a million Salieris. If someone is having fun and is excited about music, I really don’t care if it all relates back to their first Beatles album, or their first VH album, or their first Malmsteen or Racer-X album. Go. Play. Enjoy.It's crazy to me how many guys spend TONS & TONS & TONS of their time trying to emulate another guy's playing.
