I just got into the new Volbeat too. Never heard them before; never would have bothered with them if not for the King Diamond collaboration. I love their more bombastic, metal-influenced tracks, but their softer stuff leaves me totally cold. I can't get into anything on Outlaw Gentlemen before track 6. But when they're less alternative and more metal they're a breath of fresh air. Their heavier stuff sounds like Load but with better songwriting, and without the taint of Lars.
Room 24 may as well be a new Mercyful Fate song. It's amazing; King Diamond should write a whole album with these guys. I'm also enjoying Hangman, Lola Montez, Black Bart, Doc Holliday and Our Loved Ones. That's less than half the album, but I'd love to hear more Volbeat in this vein. Which of their older albums would you recommend?
