This here is classic though!

My answer (and I bet I'm not alone

Big yes. 'Mouth'
and 'stage'! Yep.
But hey, all this think, don't think, at the gig, not at the gig, doesn't it come down to YES, both, depending. Wouldn't you
think ahead sometimes, improv on stage, depending on the mode you're in? My god, sometimes it's 'heard what just got played by the other bloke, now it's a mix of 'take it in, consider what you're head hands you back, a new combo of decide' or let it fly, modify or not, then go for it.. (elapsed time i don't know..what, about 20ms?..

Now comes the part I thought OP was originally asking; How do you get to where, (and whether you're in conscious or 'spirit mode matters not here I think) what comes out is exactly executed on the ax. To that particular aspect- what way could there possibly be but time, work, lots of it? I ain't there, 'it ain't me babe, no allusions here, so I'm out of here.. er, there.


I read an account once of an audition. Something along 'Host plays incredibly complex (by mere lowliest like me) jazz head, says to auditiony', play it back to me.
Carry on.
