Priest's albums are usually quite different from each other.
After Screaming, Defenders is the most closely related, song-wise.
If you want another side of Priest, check out "Hell Bent for Leather" or "British Steele"....both have heavy as hell moments, and then more commerical tracks.
"Sad Wings", "Sin After Sin" and "Stained Class" are all epic, sometimes theatric Priest, ane eack slays!!
Literally, with Priest, you'll find little to fault, although their late 80s output left a little to be desired (Ram in Down, Turbo), but both still have their shining moments.
