I've just started reading
Yellow Back Radio Broke-Down by Ishamel Reed.
I'm a third of the way through. It's a hilariously bizarre parody of Western mythology full of dumb cowpokes, capitalist ranchers, voodoo cowboy heroes and.. a native American Chief who flies a helicopter made from the refuse of ghost-towns, woven together with a plant called plastic.
Bear in mind that it's set in the 1880s and was published in 1969.
Yeah.
