There's so much amazing performance. This bk gives a great history of some of it. Other bks cd be very different. Sometimes I look at bks on subjects I'm fairly knowledgable about & think: "WHAT?! They don't even mention such-&-such?!!" This bk doesn't get that rejection. It covers Bauhaus light plays from 1922. It covers a performance of a Satie piece w/ Buckminster Fuller as one of the actors in conjunction w/ Merce Cunningham! It even gets into COUM Transmissions's 1976 Prositution show in London. Just the fotos alone are incredibly inspiring. I almost wish I'd found this bk in Arabic on the moon. Then I cd've died & gone to Earth - maybe reincarnated as an H2O molecule in a swimming pool at Al Roon's Health Club in New York in 1965 just in time to be a participant in Claes Oldenburg's "Washes". There's even a picture of Russian Futurist David Burlyuk w/ his face painted from around 1913. So much positive energy from so many people working w/o a net & we're still perpetually at war. ( )
