I grew up in the mid to late 70's and consequently Black Sabbath was a big part of my music scene back then....
Tonight I watched the A&E Biography of Ozzy which was very well done and actually funny heart warming.
I learned through all this that Ozzy (who is sober) has a movie about his life coming out..called. "Wreckage of my Past"
...see the trailer at the link below!
It looks great!
