For you guys who enjoy good music, especially if you enjoy Sabbath, you really need to check out a real innovator of their time that has next to zero recognition even though their sound reverberates through the sounds of greats of their time.

The Pretty Things.

It will sound dated, as it should, but the musical brilliance of the time is something to look back upon and marvel, IMO. Nothing close to death metal, but I will without a doubt call them a big inspiration to Sabbath who later inspired many of the bands already posted in this thread.
