Dude...for real...that jacket is awesome.
The bootleg series is a series of double discs or box sets that Columbia is bringing out. It started in the 90s with volumes 1 to 3, one 3 CD set that covered the beginning up to 93, I think. Since there is so much Dylan out there, they kept it going and it's on volume 16 now. They aren't in order, like volume 9 was his newer stuff where as volume 10 is all the studio stuff from his first 3 electric albums. If you love Dylans work, which I do, it's pretty necessary. I have most of them except the ones dealing with his beginning stuff. Not a huge fan of that period so I'll get them when I have extra cash and no other things I want.
That tour you worked on is Street Legal period and that was supposedly him at his low point before converting to Christianity. Man, that's awesome you worked on that tour. After, possibly during that period, he got born again and stopped playing anything except his new Christian songs. That's pretty cool you were there, even if you aren't a big Dylan fan, because that's a pretty significant period in Dylan history.
