La Sexorcisto is basically a light-hearted, watered-down Pantera record with a touch of Butthole Surfers in the sound.
Astro Creep is basically the prototype Rob Zombie solo record - kinda like how Prometheus is the prototype Ihsahn solo record, if that makes sense. You listen to it and you know it's well on its way to that Dragula/Superbeast/Living Dead sexy leopard elevator sound but it's just not there yet.
