I agree with you and maybe that's the same reason I couldn't play in a band because I'm a human being not a metronome. Next time I enter composition challenge on BC I'll post the bass track separately to get less brownie points.
In my teens and early 20s all I needed was long hair, loud amp, cool bass and being able to play galloping finger style and I was in.
Unless a pub punter is one of us, general public goes to watch live band to have fun.
I went to see Testament 3 years ago or so, the bass wasn't very impressive, he had technical issues and made it so obvious. Did anyone else noticed, maybe...but maybe 99% of the audience was head banging and moshing.
