Group
Avantgarde — Germany, founded October 1993

CSDb describes this as the "Illusion Tribute" intro — Avantgarde paying homage to the Norwegian group Illusion by reusing their crack intro music. Thorn coded the intro, and Henning Rokling's "Illusion Crack Intro" composition is preserved in the HVSC. Unitrax contributed the graphics. Released in December 1994, this came just over a year after Avantgarde's founding in October 1993, during a period of prolific output documented in their other ranked entry, #247 AVT-03. The tribute concept — explicitly acknowledging another group's influence through music choice — was an occasional practice in the scene, functioning as both homage and competitive positioning. Doc Snyder's page documents Avantgarde intros with a roster of coders including Suicide, Dave, Magic Man, and Jack Alien, suggesting a group with substantial membership for the mid-1990s period. Their tagline "The Leaders of new Movements" reflected ambitions that matched their output.
