Stained Class is by far my favorite next to Sad Wings of Destiny if we're to talk about the 70s Priest. Unleashed has some of my favorite versions though, "Tyrant" just slays from the live album. So much energy and I always loved Leslie's more technical approach to drums. Guess they had to fill a void Phillips left on Sin After Sin and continue on...then they went simple for 10 years! LOL
