Cassidy (Grateful Dead) - 10 minute backing track (E lydian)
A track based on the late 1980's versions of Cassidy. It starts off in E lydian, and as the jam heats up, the chord switches to F# and the mode becomes F# mixolydian (which is made up of the same notes), then returns to E and back to F# again, and then finally up to G# minor (phrygian) for maximum tension, before finally settling back down into E major. A great demonstration of how the same group of notes (basically the B major scale) can sound so different depending on the chord underneath.
