Grant and I
That's on my Christmas list! Glad to hear it gets a thumbs up.
I have to second the love for Copey's two books -
Head On in particular is amazing, the single best band biography that's ever been written.
There aren't too many individual books on Krautrock bands I can recommend - there are a couple on CAN (the one that came with the box set and
The Can Diary by Pascal Bussy), neither of which are proper biographies as such, though Rob Young has a book on them coming out next year. There's
Stretch Out Time, Andy Wilson's book on Faust, which is sadly utter codswallop, and basically sunk by his seeming hatred of every band that isn't Faust.
Which leaves Kraftwerk, who, for the most part, have been badly served by biographers. The only one I can unequivocally recommend is Tim Barr's
From Dusseldorf To The Future (With Love), which is long out of print (but available second hand on Amazon), but does a decent job of telling the story and writing about their influence on electronic artists to come. Pascal Bussy (him again) did a not bad job with his book on the band, but it's chiefly of interest for the fact that Florian Schneider rang him up afterwards and told him that the book was shit (in french!) David Buckley's
Kraftwerk Publikation is a bit cut and paste, and nowhere near as good as his book on Bowie. There is an academic title on them whose name I forget, but which is probably quite good if you like that sort of thing. But the absolute worst is Wolfgang Flur's
I Was A Robot, a self-serving piece of crap which led Ralf Hutter to call him 'a fucking nutcase'. Not seeming to have any idea about what it was that made the band so good, or the conceptual ideas behind their work, it's only of interest if you want to read stories about Flur wanking on his parent's sofa when he was a teenager.
