The sound of 40 kg of finely tuned cucumbers, leeks, potatoes, radishes, peppers, aubergines and marrows entertained a German audience at a weekend concert by the Viennese Vegetable Orchestra.

The nine-piece orchestra plays a range of original compositions on instruments constructed from vegetables - including a flute made from a carrot, a saxophone carved out of a cucumber and a pumpkin converted into a double bass.

"I would never have thought you could get sound out of a cucumber," a young woman at the concert said.

Others commented on the raw vegetable aroma accompanying the melodies.

Jorg Piringer, the lead musician, plays a "gurkophone" horn made from a hollowed cucumber, a green pepper and a carrot reed. Fresh vegetables are bought for each concert. Afterwards, a cook adds them to a big pot of soup or stew for the musicians and audience to eat.
