Released

Code

Music
Chris (Chris Ammermuller) — "Let's Disco"
Group
Dynamix — Germany, founded June 1989

This crack intro from Dynamix, released on 23 June 1989, was coded by The Syndicate and features the SID tune "Let's Disco" by Chris Ammermuller, archived in the HVSC under the Beat Machine directory. The scrolltext reveals that Dynamix formed from members of The Beastie Boys, Sharks, Droids, and Paramount — a merger of several established German groups pooling their talent. The Syndicate served as the group's main cracker while Chris provided the music. Dynamix was founded in June 1989 in Germany and used a Frankfurt postal address for contacts. This intro is closely related to #281 Dynamix Intro #1, which shares the same coder-musician pairing and represents the group's debut production. Doc Snyder's page catalogues three Dynamix intros in total, documenting the group's relatively compact but well-crafted output during the late 1980s and early 1990s.
