played with all sort of people from 16 to 50 something..and unofficially taught a couple and it always surprises me that even someone who can't play a simple boogie riff will ,usually,come up with something ..a rhythm,fill or lick for example..and i'll think yeah.nice and pinch it..[sorry former "students" ;)
I usually ended up playing with less technically competent guys so i stuck to rhythm,to give a solid base for improvs etc,and i always like great rhythm players.Always listen with your heart and ears and try to be [humble and] restrained. I can vary so wildly from day to day...when not playing regularly with others..that i find it hard to slag off someone's playing or to give a criticism,in any way......what do you go for,if you made the audience cry,laugh or be sick from your deafing sonic terrorism do you worry that your playing is not as intended...? I know i am not the worst and will never be the best, but, God forgive you if you tell someone they stink..cause the next day it might be you..if they press you, you can always inform them nicely how to get...more advanced.
BTW,One of the better players on the local scene [my former teacher] is so shy he will play with his back to the audience
..perhaps that's a little too humble..but, it's a very difficult area.
My basic take is..what do you get if you have four guys with instruments going their own way..cacophany..and 4 guys playing together,giving and taking...music.
If you think you're so much better you'll never stay in a band,because you'll be trying to outdo everyone.
Accuracy,you say? hmm interesting concept..
