Thanks, I hear what you're saying. Glad there's others playing gigs with backing tracks. I think a lot of what's bothering me is that I can't play these as a solo jazz guitarist without a backing track. So I'm thinking I shouldn't be playing at all in public until I get to that level which could be years or forever.
If my laptop broke went out I'd be screwed. On the other hand, I think of some of the greatest guitar players like Freddie Green who never even took solos, they just backed up the band. But a real band.
