20CC was a Dutch c64 music group, who did music for both games and demos. EVS invented the world's fastest music routine, which took only four raster lines, and released it with a version of his own intro music for an exclusive crack intro he made for the group Enigma.

The group became a subgroup for Amok late 1989, but it didn't last long and by december they were on their own again.

Some news stated that Beatmachine had joined early 1990, but this is incorrect.
