George Clinton/ Parliament/Funkadelic

George Clinton is part of that the lineage (Sun Ra, Yma Sumac, etc.) that makes a pretty good argument that at some point space aliens invaded earth and took the form of musicians in a variety of genres. Space aliens or no, if the British Empire had been run by Parliament (the group) instead of Parliament (the government body), the world would be a much cooler place.
