History

Released
July 1988
Group
The Riffs / Front — Sweden

CSDb catalogues this as the "Front of Riffs Intro" — a joint production between The Riffs and Front, a Swedish group founded in July 1987. Released in July 1988, no individual credits for code, music, or graphics are recorded on CSDb, and no SIDs are listed. The cooperation between Front and The Riffs suggests a close relationship between the two Swedish groups during the late 1980s. No entries were found on Doc Snyder's page, Demozoo, or other scene archives for The Riffs. Comments on intros.c64.org from Daison and Rough in 2011-2013 confirm some community awareness of the production. Sweden was one of the most active C64 scenes in Europe, producing major groups like Triad, Fairlight, and Byterapers, alongside smaller outfits like Front and The Riffs whose output was less thoroughly documented. The spare archival record is typical of mid-1980s Swedish cracking groups that operated before systematic scene databases existed.
