"The Large Hot Pipe Organ is the world's only MIDI controlled, propane powered explosion organ. The LHPO's pyro-acoustic explodo-rhythmations will throbbatize your earholes and dance-ify your booty and make you realize what "Industrial Music" REALLY means!
"Performing live at contemporary art festivals throughout Austria, Germany, Denmark, and Holland, the LHPO is an experience of sound, light, heat, rhythm and fire you won't want to miss."
(At least it was, as of a couple of decades ago.)
