Thanks to RU Sirius and Mondo 2000 on Twitter, I just found out about @GumbysBand, an account that posts The Gumbys (Gumby and Pokey's band from the 50s/60s kids claymation series) playing rock, pop, and avant garde classics.
Here they are doing NIN's "March of the Pigs."
And the "Twin Peaks Theme."
And Eno's "Baby's on Fire."
