Mike Silverman is That 1 Guy who invented that one instrument he calls "The Magic Pipe". He spent a month creating his one-man-band harp/bass/pipes/drums-esque multi-instrument by scavenging hardware stores. Two strings of different pitches are attached to the pipes, one grounded and the other maneuverable. Triggers in the pipes play samples when struck, a cowboy boot strikes the kick drum, an electric saw, well, saws, and billowing smoke tops the whole thing off at shows.
These are photos from concerts where That One Guy played, so they may be of other bands that played the concert as well.
