I just bought a Judas Priest box set from a fellow forum member with every album. I'm enjoying listening to each CD, especially because I didn't listen to a ton of Priest growing up.
Great stuff! Cool unison-main lead as well.
One of my favourite Priest songs ever. And I really like Halford's Live Insurrection version as well; super-heavy and tight.
I have no material to shamelessly plug yet, but my own band has started a side project, Defenders of the Beast, where we do a Maiden & Priest only tribute.
Stained Class is also one of the few songs where my Boss RE-20 Space Echo comes in use (Victim of Changes, Starbreaker and Diamonds and Rust being the others), because of the tap tempo + a loud repeat setting.
