Amon Düül II x 1969/1971
There really is no end to the serpentine jamming that Amon Düül gets into. The various line ups might have had varying impact on music, but a good chunk of it, in general, is pretty decent.
That clip up top even made it into Niklashauser Abfart, a 1970 Rainer Werner Fassbinder flick from 1970.
