Group
Acrise — Germany, founded 1990

Acrise was a German cracking group that punched above its weight in the early 1990s, and this December 1991 intro shows why: Crossfire — a Danish coder who later moved on to Motiv 8 and #1 Fairlight — built a compact cracktro featuring raster-bar color cycling, a horizontal scroller, and an unusually rich music selection drawn from four different SID composers across three groups. The multi-tune jukebox approach gave each crack release a slightly different musical identity. It shipped on at least seven cracks including Dizzy — Prince of the Yolkfolk +2 and Fireman Sam +2.
