From Christian side - anything form Elefante bros...if it's too slick then slick is what i like

The Brave's first one is really really good, then Barren Cross - Atomic Arena and State of Control, then X-Sinner's first one, Guradian - Fire and Love etc. Anyways, 80's rules!
Then for secular stuff...there is two things pop into my mind first: Dream Theater - Images and Words and Metallica - Master of Puppets
