This tubulum, inspired by the Blue Man Group, was built and designed by Marc. Marc’s son Cavin played it full time with Marc for two years as “The One Man Band, and Son.”

In 2015, Marc built 2 tubulums:

  • The 1st attempt was at wearable version to play with his backpack drum kit but awesome sounding low notes made it to heavy.
  • The second is pictured on this site a lot, but never reached the original goal of being part of a One Man Band Rig. Drums, keyboards, and more were not added because the summer fair season started and only the PVC portion was complete. With no rehearsal by either Marc or Cavin, it came out of the truck at the 1st fair of summer and Cavin said: “I’ll play it.” Cavin’s performance became a game changer.
  • pipe-instrument-formulaThe 3rd Tubulum, is 204 feet of 2 inch PVC pipe and fittings in 33 notes or tubes. The PVC is mounted through 3 sheets of plywood which attach to a custom aluminum frame welded by the late, John Welde, who has a bear show. It’s built for easing miking, portability and playability. Here are some pics of the three versions and the equation for the pitch of sound (or air) in pipe lengths.

Before playing Tubulum, Cavin has excelled on drums and 6 and 7 string guitars. He also plays percussion, bass, keyboards, and at one point may have been the youngest One Man Band in the world. See video below.
