I asked about this the other day and I think this is the right place to start it.
I'm not too sure how to organize it? A thread for each mode, key or style might make sense, but I don't want to start plastering stuff all over the joint.

Anyway, I had trouble finding a Dorian back track where the major 6th actually sounded good, so I made one myself- it's a bit cheesey in that typical backing track way, but what do you expect!
