The interesting bit about this backing track is that it travels between the Dorian mode and the Aeolian mode. You get to pick and choose between A Dorian key center approach or treating the Am11 as A Aeolian and Em7(#5) as E Aeolian in the first half. On the second half of the progression you can play Aaeolian all the way though. Hope you guys like it!
