You are an EXTREME minority judging from my experience in watching 1000's of booties shake to 1000's of "incorrect" bass lines.
Sorry, I'm in a Rush tribute, hopefully ready later this year. There's not going to be many "booties" shaking (unfortunately) and if I don't play it note perfect, the musicians in the audience will be going down the checklist.......wrong........wrong............wrong...............and so on.
I couldn't deal with that.
The Rush fans want to hear the music played correctly and I've seen enough cover bands and some tributes just choke playing Rush.
I do not settle for less than my very best and to play it exact is my main goal. And there's not much wiggle room playing Rush music. The audience of Rushfans don't need to see yet another band play
their version of Rush songs. Save that for a cover band then.
But, no matter what I'm learning to play, I want to play it correct. If I want to, once I have the part figured out, I can play around with it, but that is not in front of an audience so when it comes to live, especially playing Rush, I want it spot friggin' on. I want to make sure that the ONE person in the venue watching and LISTENING to me play, hears what they expected to hear.
