It's impossible to think about 'dub' without thinking about the late Osbourne Ruddock - the great King Tubby, the singular most creative human being of the great many who've plied their trade behind a mixing desk in the name of reggae since the early 1970s. Dub may well have existed before Tubbs raised its profile to almost unimaginable heights, and it has continued to exist in the 21 years since he was senselessly slain in 1989.
