from ubu...yikes...there is anoverhwleming amount of stuff, yes.
my band has a page: clairaudient. the track is older (about a year) but i stil kinda like it.

when i started cruising around the site, i was interested in sound poetry (still am): jaap blonk, henri chopin, bob cobbing...you get crossreferenced to recordings by the dad folk who set this tradition into motion--hugo ball, tristan tzara.....and especially kurt schwitters
there are alot more folk on the site who do sound poetry, but the names escape me (it is early in the morning)...you can check out a huge range from the sound poetry today links.
on a parallel tip: brion gysin, willam s burroughs
the john cage and sun ra record is great and really hard to find now--you can download it......the cornelius cardew page has some great stuff (eg a performacne of treatise, paragraph 1 of the great learning) and some of teh maoist "revolutionary" songs he did near the end of his life--i think they are kinda sweet, but not everyone agrees.
there is some musique concrete (basically a variant of early tape music---more or less) pierre schaeffer....a generation later, goign in a different directionw ith a parallel approach---tod dockstaeder
david moss is cool--a great percussionist and loopy vocal arranger...
another huge area within ubu is about fluxus. my friend (who runs the site) takes fluxus in a broad sense, and so includes stuff from la monte young (both in the regular mp3 archive and in the aspen magazine section) through most of the usual suspects (main june paik, charlotte moorman, macunias, henry flynt) to tony conrad---it might be easiest just to search fluxus and loose a day or two checking it out.
plunderphonics: john oswald, the tape beatles. you can get a bunch more stuff from/about these folk at
www.detritus.net too.
o, and the gertrude stein page is just great. no-one reads her stuff like she does. i am a fool for it. can't help myself.
it is a huge huge resource. i spent maybe ten minutes on this scrolling through the mp3 archive index page and i know that i am not mentioning stuff that i think at least interesting. but cruise around on the planet ubu--it is an almost unbelievable resource.
oh, and this:
