Here’s an entire orchestra made up of discarded automobile gas tanks – “Gas Tank Orchestra is a trash-picking do-it-yourself reprocessing project featuring electro-acoustic instruments built from junked automobile gas tanks salvaged from New Orleans’ side streets. The tanks have been fitted with strings, pipes, hoses, mouthpieces, etc. and born again as bass, harp, zither, brass, reeds, kalimba, flute, didgeridoo, and percussion.” [via] – Link. & sample here.
