The Due Capi was invented and created by Oliver DiCicco of the group Mobius Operandi.

Italian for "Two Heads", the instrument is made from aluminum, wood, drum heads, and contains piezo pickups.

A convoluted maze of chrome plumbing pipes rises up from a jet-black column. Each pipe is capped with a saxophone mouthpiece.

On the Due Capi, two separate mouthpieces lead down through a series of tubes and valves to a common air chamber, so that the players' breath interacts, pushing and pulling as they blow.

DiCicco started building instruments back in the early 1970s, inspired by the example of Harry Partch.
