After owning the white vinyl version of Soldiers Under Command, I owned the original "controversial" first cover of To Hell With The Devil, which featured a group of angels beating up on a demon that looked like...your average metal head. Down to the Randy Rhoads model Jackson guitar he held in one hand.
I like to think someone eventually saw the cover and said "for fuck's sake, guys, you're selling albums to people who look like this, what the hell are you doing?" and the album was changed to a plain black sleeve. So it looked like Spinal Tap.
I really liked Stryper, though, as they were a pretty talented melodic metal band, but the second Honestly broke big the writing was on the wall for me with them. Calling On You was catchy enough that a carload of drunk metalheads would sing along with it, especially the end...as me and my friends did fairly often.
