The only post-Ozzy albums I own are Heaven and Hell, Born Again, Eternal Idol, a best of the Dio Years compliation, and the 2009 Heaven and Hell album (The Devil You Know).
The Ozzy era will always be my favourite. The last two from the seventies are perfectly good albums. If anyone other than Sabbath made them, they'd be called classics.
The Dio stuff is OK, but a bit repetitive. Sabbath used to have a jazzy groove to their early songs. It wasn't all doom and gloom, all the time. It's pretty much all metal, all the time in the Dio era.
Born Again is surprisingly good. It's probably their overall heaviest album. Haven't delved far into the Martin years, and i probably don't need to go any further than Eternal Idol.
Looking forward to the new album with Ozzy later this year, and I can't wait to see them on tour next Monday here in Melbourne
