Simply put: this is where metal came from. Add early Rainbow to Sabbath and throw some Zeppelin lyrics, Blue Oyster Cult harmonies and a dash of punk spirit, and you have the recipe for British heavy metal pioneers Diamond Head and Iron Maiden. So you kids should buy it. That aside, the album stands on its own as a progressive masterpiece: This is easily among Blackmore's finest moments in terms of composition and performance, and the first great example of neo-classical heavy rock. From the opening spiral of organs on "Tarot Woman" you know what you're going to get: Dazzling musicianship. Also features the talents of Cozy Powwell, who is excellent, and Dio, whose voice is amazing (if not his lyrics ;-> ). Worth the purchase for "Stargazer" and "Light in the black" alone.
