sometimes I still listen to this in the night with the lights off. quite scary, really, try!!! it seems that evil itself (under which form, who knows ,-) inspired those 4 monsters to conceive in 1969 such an earthquake for the contemporary rock music. I can't imagine being there while beatles, rolling, doors, hendrix, the woodstock' spirit and all the 60s music were still around and listening to this for the first time!!! it's still shocking, what impact could Black Sabbath have had at the time!... is there anyone writing here old enough to tell this to me?

This album is hystory. Ozzy's voice and Tony's guitar, the seed of something new.

In my opinion this is one of the best hard dark rock album ever made. Black sabbath did hear sounds and atmospheres that in their hardness and darkness had never heard before. The Voice of Ozzy is incredible, it seems made for this album.
