Horace Swaby (June 21, 1954 – May 18, 1999), known as Augustus Pablo, was a Jamaican roots reggae and dub record producer, melodica player and keyboardist, active from the 1970s onwards. He popularized the use of the melodica (an instrument at that time primarily used to teach children music in the Jamaican public schools) in reggae music. He was a committed Rastafarian.

He was born in St. Andrew, Jamaica, and learned to play the organ at the Kingston College School. It was at that point an unnamed girl lent him the melodica. Fascinated by the instrument, Pablo rarely put it down. He also met Herman Chin Loy, who after working at his cousin Leslie Kong's Beverley's record shop, had set up his own Aquarius store in Half Way Tree. Swaby recorded early tracks including "Higgi Higgi", "East of the River Nile", "Song of the East" and "The Red Sea" between 1971 and 1973 for Chin-Loy's Aquarius Records. Chin Loy had previously used the name Augustus Pablo generically for keyboard instrumentals recorded by Lloyd Charmers and Glen Adams, and Swaby took the name for this recording.

King Tubby (January 28, 1941 – February 6, 1989) was a Jamaican electronics and sound engineer, known primarily for his influence on the development of dub in the 1960s and 1970s. Born Osbourne Ruddock, Tubby's innovative studio work, which saw him elevate the role of the mixing engineer to a creative fame previously only reserved for composers and musicians, would prove to be influential across many genres of popular music. He is often cited as the inventor of the concept of the remix, and so may be seen as a direct antecedent of much dance and electronic music production.

Mikey Dread stated "King Tubby truly understood sound in a scientific sense. He knew how the circuits worked and what the electrons did. That's why he could do what he did".

King Tubby's music career began in the 1950s with the rising popularity of Jamaican sound systems, which were to be found all over Kingston and which were developing into enterprising businesses. As a talented radio repairman, Tubby soon found himself in great demand by most of the major sound systems of Kingston, as the tropical weather of the Caribbean island, (often combined with sabotage by rival sound system owners) led to malfunctions and equipment failure. Tubby owned an electrical repair shop on Drumalie Avenue, Kingston, that fixed televisions and radios. It was here that he built large amplifiers for the local sound systems. In 1961/62 he built his own radio transmitter and briefly ran a private radio station playing ska and rhythm and blues which he soon shut down when he heard that the police were looking for the perpetrators. Tubby would eventually form his own sound system, Tubby's Hometown Hi-Fi, which became a crowd favourite due to the high quality sound of his equipment, exclusive releases and Tubby's own echo and reverb sound effects, at that point something of a novelty.

Jacob Miller (May 4, 1952 – March 23, 1980) was a Jamaican reggae artist who first recorded with Clement Dodd. While pursuing a prolific solo career, he became the lead singer for reggae group Inner Circle with whom he recorded until his death in a car accident at the age of 27.

Jacob Miller was known as one of Jamaica's most distinctive vocal stylists, with a trademark vibrato he used to accent his performance.

He was born in Mandeville, Central Jamaica on May 4, 1952 to Joan Ashman and Desmond Elliot. At the age of eight he moved to Kingston, Jamaica where he grew up with his maternal grandparents. In Kingston, Miller began spending time at popular studios including Clement Dodd’s Studio One. He recorded three songs for Dodd, including “Love is a Message” in 1968, which the Swaby brothers, (Horace, later called Augustus Pablo, and Garth) played at their Rockers Sound System. While the song did not garner much success nor maintain Dodd's attention in Miller, it resulted in Pablo’s sustained interest in Miller.

Looptroop Rockers is a hip hop group from Västerås, Sweden. The members are rappers Promoe (Mårten Edh), Supreme (Mathias Lundh-Isen), DJ/Producer Embee (Magnus Bergkvist) and CosM.I.C (Tommy Isacsson). In February 2007 CosM.I.C, who had been a member of the group since the beginning in 1993, decided to focus on designing and maintaining looptrooprockers.com and not to be an active member of the group. He however rejoined the group in 2010 as Promoe announced at a concert in Helsinki on May 19, it was officially announced on their website on May 21. On their fourth album, Good Things, the group changed its name from Looptroop to Looptroop Rockers, a name they've used unofficially for some years prior to the change.

Looptroop was formed in 1991 by Promoe and Embee. The two had met while attending school in Västerås and were still in their teens at the time of the group's inception. Cos.M.I.C joined shortly thereafter and in 1993 the group independently released their cassette-only debut EP Superstars, which was followed in 1995 by Threesicksteez. By the time they released their third cassette, From The Wax Cabinet (1996), long-time associate and frequent collaborator Supreme had become a permanent member of the group. It was in the pre-DVSG time when Promoe and Cos.M.I.C were also part of a group of graffiti writers called the "BIF" (Babylon Is Falling) crew in Västerås.
