There was a series of programmes on Radio 4 in the UK about home made instruments. At the end of each programme they recorded the instrument playing a tune, and each different instrument on successive programmes did the same, and at the end they edited them all together, it was great. The most interesting instalment was from Oz where some guy has built loads of different instruments from objets trouve, and very nice they sound too, called something like the bush orchestra I think. I remember The Barrow Poets, where the double bass was hand built, with useful additions like a shelf for the player's beer.
