SPOILERS MAYBE BUT NOT REALLY
Iommi is absolutely on fire. The doom in these riffs is phenomenal. Geezer sounds great too. The bass tone sound a tad over processed, but still great. Brad Wilk did a good job at playing well, and powerfully, but also kept his place in the reunion. Didn't overplay, just rocked out. Ozzy has a few standout moments, but overall I'd have to say he's the weakest link on this album. I ge that he's old and obviously unable to perform like he used to, and given that he did a good job. Saying that he's the weakest link isn't saying that he's weak, the others just performed better.
Standout tracks for me are: Dear Father, Loner, Zeitgeist, and End of the Beginning.
I'm holding this at a 7.5/10 for now. I forsee it getting better with age.
