Hey all
Backing tracks, jam tracks and more backing tracks. Where do you get yours? Are they free or commercial? Do they have chord charts? Anything else good you look for?
Lately I've been looking at finding more backing tracks to play with and there are of course, a plethora of them available online. I've been using them to just jam with and improv over but also for practising specific things, like focussing on different notes and how they change sound compared to the musical context; like hitting different chord tones on the change, or before or after the change to see how it affects the tension and resolution of the notes etc etc. I've found the quality to be massively variable and many don't include chord charts or any information.
I can, of course, create my own and that's fine, but sometimes it's good to play along with something that you wouldn't have played/written yourself, something that takes you out of your comfort zone and introduces new ideas. I'm always looking for ways to push myself and never feel I've reached my potential, even after 15 years of playing 
So anyway, I thought I'd ask this knowledgeable community what they like to play along with and where they get them
