a few more suggestions for inclusion:
p-funk (parliament-funkadelic) should be on the list---for their early stuff (through america eats its young--great guitar band in the funkadelic guise...)
i would suggest soft machine again. for your head, sir.
for everyone's head. the first two albums. popmusic as headfuck.
gong: totally necessary. they were a great great strange strange band...their early stuff in particular, through the teapot gnome trilogy. they were not as big in the states as in europe. but their recordings are worth tracking down.
daevid allen: the first guitarist from gong, espcially his "banana moon" record, which is a classic
acid mothers temple. for guitar-driven music, they are the best i have seen in years. they single-handedly made me remember why i liked rock in the first place. maybe they could help you, if your faith in all this starts to flag.
