Different Every Time

I never could do it.  I never will do it.  I have no set list. I have a list of songs that I refer to as the  Dead Air List.   I pull from it if & when my mind goes blank as to material that I know.  It's a memory shaker, Title and Artist nudge.  I could not possibly write everything down I was gonna do & in what order for my day let alone for someone elses enjoyment...
It is different every time, no two audiences are the same.  There is a heart beat that never has the same cadence.  The mood, the air, the feel of it or anyone & everyone.   I could never commit to a set list because of this.  I wait for it.  It is one of the things in life that is a surprise. 
When I was asked to play a blues bar after doing a very country/rock gig, I didn't think we had enough material to pull it off successfully.  I used to work with a guitar player that said the difference between a country gig & a blues gig in his world is the SGF factor.   "The Screaming Guitar Factor"   He said.. put an edge on it.  He then showed me how he proposed to make his theory a fact.  He convinced me in seconds.  You can make any song feel a certain way if your heart is into it.   You have to be open to it to feel it when it comes from an audience.  Not always is it a welcomed feeling lol.  Not always is it wine & roses, sometimes you open yourself up to hostility & you have to tap into it... play for it & either ride that ride or change that mood, if they let you.    
I never know what I'm gonna do when I get there. 
The only time I know for sure what I'm gonna do is when I have something new.
Above all else, negative vibes, happy vibes, sad vibes, angry ones... the ones that take over them all is the enthusiastic ones.  No matter what is going on in a room, if someone is enthusiastic it spreads like a plague.  It isn't always the performer that brings it, but it is always an entertainer who can bring it in, spot it & use it to make that heartbeat thump as one.     Wha la, the show must go on.
