3 Key Workout Backing Track 

Cycle of 3rds through a cycle of major 3rds. Nice work charting it all out and making it easy!

Sounds awesome. I really want to hear someone like Beck or Chris Poland play over it

This is pretty interesting, playing around the key is something you learn in the beginning then you forget to try to learn the changes and sometimes you forget playing the key is important. This is the kind of changes you listen in a record and think "how these motherfuckers are playing theses changes!?" in the end they are weaving through the keys not each chord.
