Fucking hell could Ozzy's vocals be any more Protooled? And the vocal production sounds way too warm. Would've been nice to have some echo on it (kinda like you hear with Jim Morrison on the first Doors record - haunting as fuck, that sound).
The bass tone needs to be a bit more rounded, sounds too ... well, "modern". It takes away from the doomishness imo and makes it more modern rock.
Not a bad song though, surprisingly NWOBHM in parts. I'm not digging that production though, it's just too "safe" sounding.
