A veteran of the U.K. grime scene, Terror Danjah was a well-respected producer known for his work with N.A.S.T.Y. Crew (which included notable MCs Jammer, D Double E, and Kano) and Aftershock, in addition to solo material on Planet Mu, Hyperdub, and Tru Thoughts. His brash, kinetic productions, easily recognizable due to the frequent presence of his signature gremlin-like robotic cackle, added an extra dose of suspense to the syncopated rhythms of U.K. garage, and played a significant role in helping to influence dubstep. After rounding up productions from the first decade of his career on Gremlinz: The Instrumentals 2003-2009, Terror Danjah branched out with the vocal-heavy full-lengths Undeniable (2010) and The Dark Crawler (2012), all the while releasing a slew of singles and compilations, many on his own Hardrive Records.

The London-based artist began DJing at house parties as a youth, and eventually gave this up around 2001 in order to concentrate on producing. He first began releasing 12"s in 2002, appearing on small U.K. labels such as East Iz East Recordings and Solid City Records. His production for tracks such as N.A.S.T.Y.'s "Cock Back" (2003) helped establish grime as a genre, while his productions/remixes for U.K. soul singers Shola Ama and Shaznay Lewis (of All Saints) helped give the sound some mainstream exposure. He released several Industry Standard solo EPs on Aftershock, in addition to producing tracks for the Aftershock crew, many of which were compiled on Shock to the System: The Album in 2007. The disc's 20 tracks included verses by Wiley, Tinie Tempah, the Ragga Twins, and others.

Despite Terror Danjah's well-respected status among grime devotees, his name wasn't as recognizable outside the scene until 2009, when Planet Mu issued a retrospective collection of his productions titled Gremlinz: The Instrumentals 2003-2009, as well as the Industry Standard, Pt. 4 EP. He subsequently became more prolific than he was during the 2000s, with another Planet Mu release (Power Grid) as well as two early singles on Elijah and Skilliam's renowned Butterz label appearing in 2010. Dubstep pioneer Kode9 signed Terror Danjah to his highly acclaimed Hyperdub label, which released numerous singles in addition to full-lengths Undeniable (2010) and The Dark Crawler (2012). Both albums mixed vocal tracks with instrumentals, incorporating elements of house, R&B, and drum'n'bass while remaining true to his visionary sound. He co-founded Hardrive Records, which issued records by Joker, D.O.K., Mz Bratt, and others.

In 2014, Terror Danjah collaborated with Four Tet, releasing a 12" single titled "Killer" on the latter's Text Records. His single "Juicy Patty" appeared on Dusk + Blackdown's Keysound Recordings label in 2016. Following a string of digital EPs and compilations on Hardrive, he signed to Tru Thoughts and released the mostly instrumental full-length Invasion in 2019. Following years of health issues, Terror Danjah passed away in 2025. ~ Paul Simpson, Rovi
