I never heard Chapter VI or Dactylis Glomerata,or whatever it is called.
I do have FROM THE 13Th Sun, and do like it a bit.
It just isn't classic CANDLEMASS though still, ya know?
I think what they are doing with Rob now is more in line with the classic Candlemass sound.
Now, when I say this, I'm not claiming that it's a deadringer of an example. With that said, Chapter VI reminds me a bit of Tony Martin era Black Sabbath. I'm not sure why, but that's just the vibe I get from it.
I haven't heard any of the albums to be honest between when Messiah left and when Messiah came back, though I have listened to the two new ones. I think those definitely have a classic vibe or at least King of Grey Islands does. I just haven't been able to get into Death Magic Doom.
I actually prefer Rob more than Messiah. That may sound like blasphemy but I find Rob has a more clear and a stronger voice to boot. Messiah's vocals sound a bit goofy to me sometimes.
I don't really prefer one over the other, but Rob is a great fit imo.
I'm not too big on Rob in Candlemass. He's amazing with Solitude, and one of my favorite singers, but I just don't like his voice on a lot of the Cmass stuff.
Ouch...I think Rob could sing for Pain of Salvation and I'd like it!
