you want a list of out there and weird refer to this:

one of the weirdest albums to me is Brainticket's Cottonwoodhill, krautrock in the late 60's through the 70's definitly had alot of weird and out there moments in the rock movement along with the astonishing pysch-folk-underground from around the same time period... i think that first Fifty Foot Hose album is weird, Joe Byrd and the Field Hippies album The American Metaphysical Circus (off shoot of of THe United States of America), White Noise Electric Storm, definitly... The first Red Krayola album, The first Comus album is pretty bizarre, The Edgar Broughton Band was pretty bad ass and sorta weird. this is just scratching the surface.
