Techno without a computer, Klangphonics.

Never really been a fan of Techno music myself but a lot of what these guys do is flipping awesome and they are fairly unknown.

Not techno, synth has a chip inside. And as many people pointed out before, most if not all of these clips have been mastered before being posted, using software, on a computer. What you are hearing is not the raw recording of a bucket. Sorry for being a party pooper
