Tuning is down one half-step (Eb-Ab-Db-Gb-Bb-Eb).
Song is played in the key of Gb maj but the solo here is done with an E min
pentatonic (which is really an Eb min because of the tuning.)  The chord
progression is basically 1-5-4 (G-D-C), 1-5-4-5 (G-D-C-D) with some
changes thrown in here and there.
