Andrew Jacobs here,
As I've previously mentioned in one or two of my interviews with the ladies of the excellent Black Sabbath tribute band Black Sabbitch, Sabbath is by far my #1 favorite metal band of all time. And like the majority of Sabbath fans, my favorite era is the Ozzy era of the 1970s.
Having said that though, the Tony Martin era of Sabbath from 1987-1991 and 1993-1996 is so unbelievably underrated, it borders on criminal. To that end, here is a video documentary of that era that I found on the Black Sabbath message board. I hope to have an interview with the great Mr. Martin soon as well, so stay tuned for that.
