I used to be a die-hard metal guy since I start playing guitar/bass until around 1995, when I started getting into funk, jazz and everything else, but I still listen to a lot of metal throughout the day.
How about that new Black Sabbath album? On first listen, I wasn't too impressed, but after a few days, I think it's pretty good! Really digging the bass sound, and Ozzy is singing pretty good. Too bad Bill Ward wasn't part of it - that really would have been the icing on the cake. Tommi Iommi is a genius in my opinion.
