Query: Great Sleeper CD

This is a one shot wonder for this band, strayed away from the Ozzy & Dio sound, but came up with a gem with Ian Gillian as the front man. The riffs and style is what Black Sabbath is all about, heavy, heart punding, head banging msuic. The album is a sleeper, but a great value and a collectors item if you are a Sabbath Fan!
