History

Released

Music
Future Freak (Kim Christensen), Laxity (Thomas E. Petersen)
Charset
Mr. Cursor
Group
Zenobits — Germany, founded 1988

A three-SID jukebox with two Danish composers — Future Freak (Kim Christensen) and Laxity (Thomas E. Petersen) each contributing compositions, including Laxity's popular "Fairlightz" and "Public Enemy." Mr. Cursor provided the charset. Zenobits was a German group founded in 1988. No coder is credited on CSDb. Released on 19 September 1988, this arrived during the period when German groups routinely attracted Scandinavian musicians through mail-trading connections. The HVSC preserves all three tunes. Laxity's "Fairlightz" — a composition named in tribute to #2 Fairlight — circulated widely across the scene. Doc Snyder's page documents Zenobits. Mr. Cursor's charset work appearing yet again demonstrates his extraordinary reach across the German and international scene.
