Iron Cat (Alain Hertenstein) — Avantgarde Intro

This crack intro from the German group Avantgarde is catalogued on CSDb as release #251695, simply titled "Avantgarde Intro" and dated 1995. Code is credited to Dave, graphics to Skywolf, and music to Swiss composer Iron Cat (Alain Hertenstein) using his composition "Avantgarde Intro," preserved in the HVSC — a custom SID written specifically for the group. Doc Snyder's page confirms Dave as coder, Skywolf as artist, and Iron Cat on music for this specific intro. The scrolltext announces a crack of "Tim Tris" from Agony Design, provided by Intruder and cracked by Thorn. Greetings extend to Empire, Demonix, F4CG, SCS+TRC, Atlantis, Excess, Chromance, Fairlight, and others. Avantgarde was founded in October 1993 in Germany. This is one of several ranked Avantgarde intros, alongside #247 AVT-03 and #652 AVT-01.
