History

Released
28 May 1988
Group
XAKK — Sweden, founded August 1986

A crack intro from XAKK, a Swedish demo and cracking group founded in August 1986 by Knatter and Jolly Cracker. CSDb matches this to a release dated 28 May 1988, with music ripped from Matt Gray's "Professional BMX Simulator." No code or graphics credits are listed. The group — also known as XAKK Cracking Section — dissolved in 1990 after producing 79 releases. Members included Cleo, Mr. Vivace, Black Adder, Closseau, and Mr. Mezzo, among others. XAKK earned a notable CSDb community rating and was recognized for a "unique demo style," particularly their acclaimed "Bound to Be Best" series. CSDb explicitly notes that this Swedish Xenon-era group should not be confused with the Dutch group of the same name. Other XAKK entries in this collection include #710 XAKK 03 and #801 XAKK 05. Founded in 1986, XAKK predated many of Sweden's most celebrated scene groups.
