This is musician Julian Corrie’s “Polybius,” a song created with sounds from hard drives, floppy disk drives, a Commodore 64, and a SEGA Mega Drive. If you’re wondering where this video was shot, that’s an empty indoor swimming pool. According to Corrie, “The unusual ensemble (controlled live via MIDI) are given a last curtain call in a nostalgic farewell to forgotten friends.” Corrie wrote and performed the piece, which was shot by James Houston.
