not actually sure aboiut the labanalysis connexion, but there are a few
scraps of info about william forsythe's cd-rom ("improvisation
technologies of self meant to govern") on the web at
there's a quicktime sample from the cd at (though, in truth, its only
value is probably as a taster)
and there's some general info from the publisher, zkm...
http://domini.zkm.de/projects/bildmedien/improvisation.de.html ( as
above, in german)
if you get hold of a copy (or if anyone _has_ a copy), needless to say,
i'd be very interested in details.
