This discussion reminded me of the first DT show I attended with my wife. We went to the 2nd night at The Beacon on 03/28/2002, my third show of that tour. I have no recollection of how I found out, but I knew we were getting Master of Puppets for the 2nd set. Even though I had not heard note one of that album before that night, I was open to the experience. I felt bad for my poor wife however, as this may have been a bit over the top for her very first DT experience. As the 2nd set started and we got SDOIT, I was stoked, as I would much rather have heard that song than MoP.
As the DT world found out, we got the best of both worlds that night. My wife was soon sleeping comfortably on my shoulder about half way through Battery and for the rest of MoP. (I woke her up for the encores, which she enjoyed.) She had survived one the longest (if not the longest) DT show ever, and enjoyed the ride almost as much as I did. She's since been to most of the 20 plus DT shows I've attended, and has loved them all. Over twenty years later however, she has yet to hear MoP in its entirety.
Maybe I'll break it out for our anniversary...
