Hi,
Have fun on your vacation is first and foremost ... very important ... and most useful.
I do not like to make suggestions in reading, any more than I do for listening, mostly because it is such a subjective touch, and no one knows where it comes from, and that makes it harder to read and relate to.
That said ... here are some bits and pieces, and my comments on it.
Robert Wyatt -- Different Every Time. Probably one of the most fun things to read, and valuable in terms of learning how to do something else, in music. I kinda look at it, how the heck can RW go back to being a kid on this album, then you listen to it ... son of a gun ... there it is again. Even though it is never discussed as such, the ABC thing on Soft Machine 3 is perfect, and a total "anti-jazz fan" thing, kinda making fun of the whole thing. Instead it made them famous ... !!! His music discussions are priceless ... and please pay attention to what he says about Syd Barrett! You'll absolutely love it! Also an incredible history of the time.
My Last Sigh -- Luis Bunuel (the film director) put together this, and it is a bit of history of Spain in the 1930's and 1940's and you can see how some literature survived, or was shot, and sometimes I think that "surrealism" was an intentional way of getting a laugh on the many horrors in front of these folks. A true insight into the crazy details in many of his film, and if you can, get "The Exterminating Angel", "Los Olvidados", "Robinson Crusoe" (his is the funniest!), "Nazarin", "Viridiana", "The discreet Charm of the Bourgeoisie", "The Phantom of Liberty" ... all of these highly recommended viewing for stuff that is not on the "pop music" side of things, and yet, is as powerful as anything you have ever thought in film, or music.
Future Days -- About "krautrock", the harshest term ever for music in Germany, but it is detailed and insane and well done, and is a total history of Germany through music after WW2. Very well done, all around, and the hardest part is getting past the long introduction. But learning that this was as much about each area, just like America ... and how the influences arrived and left on the same boat!
