Every real metal fan knows how much Ozzy has done for this music. This out of many of his albums with or without Sabbath is one of the best. Even thou it’s a bit short with only 8 tracks and running time of 43.26. It's an album you can listen to the whole thing. Starting of with an amazing rocking song "Over the Mountain' and ending with "Diary of a Madman". The whole album has amazing guitar work with Randy's lead and rhythm playing. Ozzy's lyrics and singing have always been some of my favorite and on this album especially. This is an album you have should get.
