Dutch producer and DJ Tommy de Roos has been mutating jungle and hardcore as FFF since the 1990s. Piling noise and distortion on top of intense, complex breakbeats and gargantuan bass lines, he was one of the early innovators of the breakcore scene, as well as its dancehall-influenced raggacore subgenre. His work throughout the 2000s, such as the -issued 12" The Feeling, consisted of violently ecstatic bastardizations of rave, happy hardcore, and ragga-jungle, and he pushed this sound further with subsequent full-lengths for the Japanese label , including 2011's 20.000 Hardcore Members Can't Be Wrong. Since the mid-2010s, he's generally toned down the distortion and produced more atmospheric, focused tracks, leading a revived jungle scene along with producers and DJs such as and Coco Bryce.
Tommy de Roos first attempted to DJ techno and rave records in the early 1990s, and began experimenting with making music from sampled tape loops, a keyboard, and feedback. After his family acquired a computer, he started using tracker software, which drastically changed his approach to music-making. He started a zine and label called Orange Socks in 1997, and released breakcore, noise, and experimental cassettes by himself, his friends, and artists he met through trading tapes. He started issuing tracks on vinyl in 2001, beginning with a split EP with Fast Forward, and followed by records on labels including , Clash Records, and Sprengstoff Recordings. That year, FFF and also organized Breakcore a GoGo, one of the first regular breakcore events in Europe. After the series ended in 2004, FFF started a similar monthly called Wreck Havoc.
