On-U Sound and the UK dub continuum

London dub and experimental-reggae label built by producer Adrian Sherwood out of his earlier Carib Gems and Hit Run imprints, formally taking the On-U Sound name around 1980; home to African Head Charge, Dub Syndicate, Tackhead and New Age Steppers, it carried the mixing-desk aesthetic of Jamaican dub into British post-punk.

Jah Shaka (Neville Powell, c.1948-2023), known as the "Zulu Warrior," was a Jamaican-born, South East London-based sound system operator who ran a roots-reggae and dub sound from around 1970. Celebrated for the spiritual intensity and heavy sonority of his single-handed sessions, he also released roots and dub records from 1980 on his Jah Shaka Music label, including the Commandments of Dub series.

Dennis Bovell, born in Barbados and raised in London from early childhood, was the connective figure across 1970s British reggae: leader of Matumbi, engineer and de facto producer for much of the scene around him, and operator of his own sound, Sufferer HiFi. In 1979 he worked out the distinctive rolled hi-hat pattern on Janet Kay's "Silly Games" with Aswad's drummer Angus, after Matumbi's own drummer declined to play it. To get UK-recorded material accepted by sound systems that wanted only genuine Jamaican pre-release, he pressed British recordings on blank or barely labelled discs under the alias "4th Street Orchestra" and used a "dinking" machine to punch the oversized centre hole that marked out a Jamaican import single. He also engineered and effectively produced Louisa Mark's 1975 "Caught You in a Lie", widely credited as the first lovers rock record. In October 1974 he was prosecuted as the alleged ringleader of a "gang" he said he had never met, after a sound clash at the Carib Club in Cricklewood turned into a public-order incident; a hung jury at the Old Bailey was followed by conviction on retrial and a three-year sentence, of which he served six months before the Court of Appeal quashed it, ruling the trial had been mishandled.

English dub producer and studio engineer, founder of the On-U Sound label, who extended King Tubby's studio-as-instrument approach into British post-punk and dub electronics; a key figure in the UK dub production lineage alongside Mad Professor.

The British tradition of custom sound-system construction that grew from Jamaican roots, in which specialist builders of valve amps, pre-amps and speakers, from Metro to Mostec, engineered the heavy dub sound of the UK dance.

The remix before the word existed: Jamaican engineers of the early 1970s — King Tubby foremost, with Lee Perry, Errol Thompson and their successors — stripped the vocal from a rhythm and rebuilt what remained live at the desk, drums and bass forward, fragments of voice and horns drenched in reverb and delay. It began as B-side economics and became a form in its own right, and its fingerprints are on remix culture, hip hop instrumentals, jungle, dubstep and every music that treats the studio as an instrument.

Osbourne Ruddock (1941-1989), the Waterhouse electronics engineer who invented dub. He built and repaired amplifiers, ran his own Hometown Hi-Fi sound, and began cutting versions with parts dropping in and out, drenched in reverb and delay worked live at the controls — first as exclusive plates for his own dances, then as a form in its own right. He trained Scientist, Prince Jammy and others, and his approach to the mixing desk as an instrument reshaped record production worldwide. He was shot dead outside his home in 1989. Per the engineer and broadcaster Mikey Dread, who apprenticed under him, Tubby built his first echo unit himself from two old tape recorders and constructed custom pressure-sensitive, spring-loaded switches for triggering sound effects, so that striking them harder or softer varied the result. Dread also credited a Tubby-built high-pass filter, applied to the snare and hi-hat, with producing the splashy "flying cymbal" sound heard on Bunny Lee and Johnnie Clarke productions such as "No Man Can Escape His Judgement" and "Jah Jah in Deh in Deh".

Psychedelic dub ensemble formed in 1981 by percussionist Bonjo Iyabinghi Noah with producer Adrian Sherwood on the On-U Sound label, fusing Nyabinghi-rooted drumming with dub studio techniques into a globally influential body of work.
