ICE-T (Rick Hoekman) — "Sound and Vision Intro"
Group
Sound and Vision [SAV] — Netherlands

A 1989 crack intro from Sound and Vision, a Dutch cracking group abbreviated SAV. The Last Dragon coded the intro while ICE-T (Rick Hoekman) composed the music — a purpose-built track titled "Sound and Vision Intro," preserved in the HVSC. The musician's handle ICE-T — borrowed from the American rapper — reflects the hip-hop-inspired naming conventions prevalent in the late-1980s scene. Sound and Vision operated from the Netherlands, contributing to what was one of the densest national C64 scenes in Europe. The group's founding date is undocumented on CSDb. No graphic artist is individually credited for this release. The Netherlands produced a disproportionate number of influential SID musicians during this era, and Hoekman's contribution here adds to that tradition. The group left a limited archival footprint — no entries were found on Doc Snyder's page, Demozoo, or in the scene press archives.
