This is a rock guitar chord progression based around the key of F#Minor. It has kind
of a neoclassical feel. The legato section is inspired by the legato section starting off the solo in Relvelation (Mother Earth) where the late Randy Rhoads (RIP) does a schorching solo. If you don't own it get a copy of the live "Tribute" album. It is filled with a lifetimes worth of great passionate music to enjoy and study.
