I have time here to get more detailed on this - I probably sound like a broken record, but I would definitely choose Zoo TV. One reason is because I was about 5 years old when Red Rocks happened, so I wouldn't have paid much attention to the music anyway, haha. I'd LOVE to go back to experience the Zoo shows at the RDS, definitely (though I listened live on the radio - next best thing). I would've liked to experience at least one Zooropa show and one Outside Broadcast show. Hell, I'd give my vital organs to go to any of the shows that featured Daddy's Gonna Pay For Your Crashed Car - that's my song, I'd have lost it if I heard this live! Of course I was going from tween to teen in the Zoo era, so imagine you're a young woman in GA and you're right in front of MacPhisto or The Fly...with a good view of Larry too! Oh the hotness sure would get you through puberty!
