Get Zakk's Book of Shadows, Pride and Glory...
Both of these are great, Book of Shadows in particular is absolutely brilliant: however, neither album is metal. BoS could possibly be considered southern-rock.
As for BLS...they are a mixed bag with me. I used to love them until I realized that Zakk kept writing the same song and that his vocals have continued to go downhill for the past 3-4 years (re: sounding like Ozzy).
-I would say skip SONIC BREW, it has some great moments, but it's still a little stunted in the songwriting.
- STRONGER THAN DEATH is awesome. Pummeling and punishing. Especially "Counterfeit God".
- 1919 ETERNAL is amazing. Best BLS album, IMO. Tight, punchy, focused, and badass.
- THE BLESSED HELLRIDE continues on 1919's wave and ends up being pretty good. Some fantastic material is on here, but it's not as good as the previous.
- HANGOVER MUSIC, I enjoy, but it's not that great. It's similar to the Pride and Glory stuff...except that Zakk's voice is completely shot.
- MAFIA has some real gems, and some real garbage. It's best just to pick some specific songs off of it, such as "Fire It Up", "Too Tough to Die", "Been a Long Time".
- SHOT TO HELL...meh. I couldn't name you ANY song that grabbed me off this album. Very recycled...very, once again: Ozzy (and that's not a good thing).
