Music
Henrik B. Jensen — "Maximum Overdrive II"
Group
Rampar — United States, founded 1988

Wanderer coded while Henrik Buus Jensen composed "Maximum Overdrive II (intro)," preserved in the HVSC. Rampar was an American group founded in 1988, one of the final generation of US C64 cracking operations. Released on 20 December 1988 — a Christmas-period release. Jensen's contribution connects this American group to the Danish musical sphere. The handle "Wanderer" notably matches The Wanderer Group's name — whether this represents a member crossover or coincidence is unclear from CSDb data alone. Rampar operated during the last months when American groups maintained competitive output before European dominance became absolute in 1989. The intro title's "Maximum Overdrive" reference — a Stephen King film — reflects the era's pop culture absorption.
