I've been a White Zombie for years, and just a Rob Zombie fan in general. When I'd heard he was releasing a solo album (Hellbilly Deluxe) I was very excited. I'd heard and loved his song The Great American Nightmare (Private Parts Sdtk) and was very optimistic about his solo debut. In short, I wasn't disappointed in the least.
With The Sinister Urge however, I was a little let down. It just didn't have the same energy Hellbilly had. Dead Girl Superstar and Scum of the Earth (also on the MI:2 sdtk.) are, in my opinion, the best songs on the album. The rest... the rest of the songs just didn't bore into my brain like Superbeast, Dragula, Living Dead Girl, et all from Hellbilly.
To me, it seemed like Rob wanted to bang something out in order to keep with his tradition of releasing an album every three years. (La Sexorcisto 1992, Astro-Creep 1995, Hellbilly Deluxe 1998, Sinister Urge 2001)
But despite the lack of chutzpah Sinister Urge seems to have, it's still Rob Zombie, and it's still better than any of the other crap you'll hear on the radio.
