I'm thinking wayyy back to 1980 or 81 about a Frank Zappa show I saw. I was really into Frank and had all of his recent releases. This being pre-CD, the early stuff was really hard to find on LP although I did eventually get almost everything. Anyway he played a 90 minute show as usual and I wasn't familiar with any of it until the encores where he did a couple of his most well known songs. I remember thinking "I'm never going to remember any of this" so I whipped out a piece of paper and scribbled down some lyrics as they went by. I'm mostly reflecting on the mental processes involved. a) If you go see someone you've never heard of, then you have to be open minded, you don't have any preconceived notions, and whatever happens, happens. Later you might think, "I really liked that one, what was it, la la la blah blah blah"... or "the guitar player was great/sucked" etc. But mostly you're just trying to figure out if you like what you're hearing well enough to buy a CD or something. b) If you go see someone whose work you know, and they play a lot of familiar stuff, then you'll be thinking, "they did/didn't play my favorite tune" and "they did/didn't play it just like the recording" or "what happened to my favorite sideman". c) If you go back in time and see Frank Zappa in 1981 when he was playing mostly unreleased stuff, you'll think "gah, what is this? what is he doing? what do I say about it later? help (I'm a rock)!"
