As the one-man band known as That 1 Guy, Mike Silverman plays an instrument of his own invention, which he calls "the magic pipe." After growing frustrated with other instruments, he designed it over the course of a month spent haunting hardware stores, collecting odd lengths of pipe and tools with the manic fervor of Richard Dreyfuss' character in #Close Encounters of the Third Kind.
Despite never having designed or built an instrument before, at the end of the process he had created something that was surprisingly tuneful, despite resembling a cross between a harp, a bass, a set of bathroom pipes, and drug paraphernalia. Two strings of differing pitches are attached to the pipes, one set firmly grounded and the other able to be maneuvered as it is played. Trigger points all over the piping play prerecorded samples when struck. There's also an electric saw, and a kick drum made from a cowboy boot is attached to the bottom.
