Here are a couple more examples of inspired sampled found-sound beatmaking.
Above, Music from a Car, by Alessandro Camnasio:
The basic idea for this project was to play a car as a sort of musical instrument. I started by placing some microphones inside and around the car. Then I recorded all the tracks on a Cubase system. I didn’t use any sampler or synthesizer to create or modify the sounds. All the sounds come just from playing the car, by patting on the windows, punching the bumper, rubbing parts made of fabric or plastic, giving fuel, playing rhythms on the wings, the roof, and so on.
Below, Beats of Boredome, by AdamPellinDeeve:
Nothing to do. Loop found sounds.
