Bronx -- Denmark, founded August 1990

Crack intro #16 from Bronx, a Danish cracking group abbreviated BRX and known by the tagline "What a Rush!" CSDb catalogues this as "Bronx Intro 01" with music by Beat (Nantco Bakker), whose "Sax-O-Maniac" is preserved in the HVSC, and graphics by Bird. Doc Snyder's page documents a separate Bronx intro coded jointly by Megatonn and Trisonic, who also shared artwork duties, with music by Mike (Michael Hendriks). In the Doc Snyder comments, a member named Byt revealed a bug in the Bronx logo where the letter N resembles an O -- a mistake that went largely unnoticed by viewers. The group was founded in August 1990 in Denmark, operating within the competitive Scandinavian cracking landscape alongside groups such as Dominators, Bonzai, and Triad. Beat was a Dutch musician whose SID compositions appeared across multiple groups' releases. With sixteen or more numbered intros, Bronx maintained substantial output from their Danish base throughout the early 1990s.
