History

Released
6 January 1988
Group
Beastie Boys [BB] & Scoop — Germany / Netherlands
Code
The Mercenary Cracker
Music
Jeroen Tel — Beastie Boys

This crack intro is catalogued on CSDb as release #61383, a joint Beastie Boys and Scoop production dated 6 January 1988. Code is credited to The Mercenary Cracker, with music by Jeroen Tel — the renowned Dutch SID composer — using a tune titled simply "Beastie Boys," preserved in the HVSC. This custom-titled composition suggests Tel wrote specifically for the group, an honour reserved for well-connected crews. CSDb lists the primary group as Scoop, indicating a cooperative release between the German Beastie Boys and the Dutch group. Doc Snyder's page lists The Mercenary Cracker as both a coder and charset designer across the broader BB intro catalogue. Beastie Boys was founded in July 1987 in Germany, and this January 1988 release came during their most active period. This sits among their lower-ranked entries, well below #16 BB-02 and #132 BB-09.
