History

Group
Avantgarde — Germany, founded October 1993

Crack intro #22 from Avantgarde, a German cracking group abbreviated as AVT and known by the tagline "The Leaders of new Movements." The CSDb search confirms Avantgarde's extensive catalogue under group ID 485, with over twenty crack intros indexed, though no specific release was matched to this production. Doc Snyder's page documents the group's roster of contributors: coders including Suicide, Dave, Magic Man (Stephan Schloepke), Jack Alien, and Rage; musicians spanning Thomas Detert, Iron Cat (Alain Hertenstein), Xayne (Giuseppe Musardo), Predator (Geir Tjelta), and The Syndrom (Matthias Hartung). The group's scrolltexts reveal connections to both American and European scenes -- members like Weasel, Deff, and Thorn were actively cracking titles through the mid-1990s. The intros.c64.org listing attracted comments from Obi Wan Kenobi, Thomas, and CenTraX. Other Avantgarde entries in this collection include #247 AVT-03 and #429 AVT-27. Twenty-two numbered intros confirm significant output from this crew.
