New song from Black Sabbath, listenable here. The negative aspects are easy to pick out: drumming is sub-par (it's hard to follow in the steps of Ward, Appice, and other past Sabbath drummers) and the drums are mixed a bit too low. Iommi's guitar isn't mixed high enough; it could sound fuller and more raw than it does. The good things are obvious, though: the overall style is classic Sabbath, and there's the interplay of Geezer's pounding bass on the low end complementing Iommi's guitar on the high end, just the way they did it back in the day.
Overall, a conservative effort but fun to listen to. Here's hoping the rest of the album isn't as over-produced (I want the rawness of the original Sabbath albums) and that they come to town soon. If they can autotune Ozzy live, it'll be one heck of a concert.
