Short answers, pulled from the story.
King Tubby was Jamaican sound engineer Osbourne Ruddock, born on the 28th of January 1941 in Kingston. He is widely cited as the inventor of the remix concept and a founding figure of dub music, having developed techniques of stripping and reshaping multitrack recordings that later became standard practice across dance, hip-hop, and electronic music production.
Tubby developed dub while working as a disc cutter for producer Duke Reid starting in 1968, initially removing vocals from instrumental versions of songs for sound system use. He discovered that individual tracks could be accentuated and rearranged using a mixer and effects units, eventually creating wholly new pieces by adding extreme delays, echoes, reverb, and phase effects to existing multitrack master tapes.
"King Tubby Meets Rockers Uptown" from 1974 is his most famous dub and is frequently cited as one of the most popular dubs ever made. It originated from a Jacob Miller song called "Baby I Love You So," featuring Carlton Barrett on drums and Augustus Pablo on melodica, and appeared on Pablo's 1976 album of the same name.
King Tubby opened his first studio in the Waterhouse neighbourhood of Kingston, Jamaica in 1971, using a 4-track mixer purchased from Byron Lee's Dynamic studio. In the 1980s he built a new and larger studio in the same Waterhouse neighbourhood.
Tubby worked with Jamaica's leading producers of the 1970s, including Lee "Scratch" Perry, Bunny Lee, Augustus Pablo, and Vivian Jackson. Artists on those recordings included Johnny Clarke, Cornell Campbell, Linval Thompson, Horace Andy, Big Joe, Delroy Wilson, and Jah Stitch.
King Tubby was shot dead on the 6th of February 1989 outside his home in Duhaney Park, Kingston, upon returning from a session at his Waterhouse studio. His death was believed to be the result of a robbery. He was forty-eight years old.
