You may have heard classic tunes recreated on barely functional pieces of electronics before, but this is a really impressive effort.
All made using:
a. HP Scanjet 3P, Adaptec SCSI card and a computer powered by Ubuntu v9.10 OS as the Vocals. (hey, the scanner is old)
b. Atari 800XL with an EiCO Oscilloscope as the Organ
c. Texas instrument Ti-99/4A with a Tektronix Oscilloscope as the Guitar
d. Hard-drive powered by a PiC16F84A microcontroller as the bass drum and cymbal
I quite like this as well.
Daft Punk Derezzed (from the Tron Soundtrack) performed on 5 Hard Drives.
