“Blizzard of Ozz” was a madman metal scientist’s creative dream. It revolutionized the way that music can still be developed. “Mr Crowley,” one of the singles from this album shows Ozzy Osbourne’s success in releasing solo works, along with the true guitar shredder Randy Rhoads. Distortion, shredding, arpeggios, neoclassical, and heavy metal are all put into this one song. This became one of the most well-known tunes that went along with Ozzy, Judas Priest, Metallica, Iron Maiden, and even John Petrucci who would be one of the main founding members of Dream Theater. Check out the song video below.
