That is literally the Holy Grail of ALL Holy Grails. I always haphazardly check the vinyl racks at record stores for it just as I'm flipping through the U2, but I only ever find 9 copies of Under a Blood Red Sky and a few Unforgettable Fires.
Didn't have it til a year or two ago Bart- its a sin, but its not a HUGE HUGE sin. At least you have a copy I had mine burned off my uncle for years til I finally bought it.
I'm sure they'll put AB out on vinyl once they re-master it...though who knows, TUF didn't get a vinyl re-release. That one's still pretty wide in circulation around used shops though, like i said- I find it every place I look. I've never seen a physical copy of AB in my life..
Only place I play them is my car so I don't have to deal with my iPod radio transmitter and get all the static and feedback. So yes, I still use my physical copy.
