Christopher John Mackintosh (born 29 December 1965, Paris)^[1] is a British electronic music DJ and producer. Mackintosh was a member of M/A/R/R/S and a DJ at Ministry of Sound in the 1990s, in addition to doing production and remix work from the 1980s onward.^[2]

Mackintosh was raised in London, where he DJed on a sound system he had put together with his brother, who was also a DJ.^[3] He held a regular gig at London's Flim Flam Club (run by Jonathan More of Coldcut)^[4] before being hired by Serious Records to put together compilation mixes, and in 1987 he participated in the DMC World Mixing Championships, winning the UK bracket.^[3] That same year he joined Dave Dorrell's Nasty Rox Inc. production crew, after the departure of Nellee Hooper, and then was invited by Ivo Watts-Russell to join a dance/hip-hop studio ensemble on the 4AD label, which became M/A/R/R/S. The group's hit, "Pump Up the Volume", was a hit both in the UK and the US.^[2]

Following M/A/R/R/S's short-lived success (the group released only one single), Mackintosh did remix and production work for C&C Music Factory, Coldcut, Tina Turner, Public Image Limited, Janet Jackson, Sly & Robbie, De La Soul, Whitney Houston, Barbara Tucker, and Whycliffe.^[2] He began DJing at Ministry of Sound in the early 1990s and concomitantly began releasing mix CDs; his residency at Ministry of Sound ended in 1996, but he continued releasing CDs into the 2010s.^[3]
