DUBCRT is a music album, interactive light synthesizer and remix-gadget released as a Commodore 64 cartridge. With music and visuals from some of the most prolific experimentalists of the 8-bit scenes, DUBCRT taps into 1960s modernist forms, 1970s dub, 2000s glitch aesthetics, and 2020s sustainable computing. DUBCRT features:

  • Eight songs ranging from ambient to IDM and drum n' bass
  • Visualisers that react to music, and that are user-controllable
  • A secret remix module that allows you to re-interpret all the music on the cartridge

All of this uses only 64 kilobytes. equivalent to 1.5 seconds of MP3-audio. This is possible thanks to clever use of resources, and by making all the graphics in PETSCII, the colourful and quirky ASCII-variant of the Commodore 64.
