Or, to be more precise, it's a didgeridoo with a curved shape that resembles a saxophone.
The Strawberry Man is a musician who got is name by wearing strawberry-themed outfits early in his career. When he encountered the didgeridoo, he was fascinated with its mesmerizing sound and decided to learn how to play it.
The didgeridoo looks like a simple pipe, but playing it is a physically demanding task. It requires circular breathing--simultaneously inhaling through the nose and exhaling through the mouth without pausing.
The Strawberry Man took his didgeridoos on tour, but found transporting them on planes very challenging. He needed a more compact instrument. The result of his experiments with collaborators is the Saxo-Didge--a didgeridoo that retains its traditional sound while fitting into a much smaller space.
