History

Released
1995
Group
Dytec (DTC) — Germany, founded 1990

This 1995 crack intro from Dytec was coded by The Last Hacker of Onslaught, with Spike of Amorphis and Estate composing the SID tune "Brick's" and Josh providing the graphics. The involvement of a coder from Onslaught shows how Dytec drew talent from beyond their own roster as the group matured into the mid-1990s. CSDb documents this intro's use in the crack of "Triss +3," among others. Dytec was founded in 1990 by The Fatman in Germany, operating with the motto "Power from the Eastside." By 1995, the group had accumulated hundreds of releases and maintained cooperation with Tristar & Red Sector Inc. The Coolart subgroup, which featured prominently in earlier Dytec intros, continued to contribute members. This is one of several Dytec intros in this collection, which together document the group's evolving visual and musical style across the first half of the 1990s.
