I like the drier vocal treatment, even if there is still the usual Ozzy, Chorused, Eventide Preset thing going on. I suppose being Sabbath they can't dick with him that much; it would be inappropriate given the context. He has zero technical ability and very limited range; he's all about the character. And that's fine. Trying to make someone like that into a pop singer is a waste of time. Really, it's Tony and Geezer's riffs; that
is that band. Now: they are Lords And Masters of the Almighty Riff. Which counts for a little. My mom could front that band and they'd be awesome.
The lack of Bill Ward is dissapoint, but Mr. Ward's heart just isn't in it, quite literally, it seems, poor guy.

That being said, have you seen the Classic Albums episode on Paranoid and heard Mr. Ward and Mr. Butler soloed? Good goddamn, that is a rhythm section! I still rate it in my top 5 rock records of all time
for a reason. It stands a fair chance of making my top 5 fave-o-rite records, period full stop done, on any given day. And most of what I listen to is classical music and old-school jazz, singer-songwriters and electronic music and things that are not rocking so very much.
That being said, Mr. Appice is not a bad drummer by anyone's standards, I don't think. I've heard him live with Sabbath, but I don't have the tapes or the means to play them anymore. (Sabbath fronted by Rob Halford was interesting, if you can find the bootleg.) As a bassist, I cite Mr. Butler as one of my biggest influences, and that is not likely to change; he's awesome. And I like his tone here.
