LTJ Bukem is the stage name used by the drum and bass musician, producer and DJ Danny Williamson (born 1967, London). He and his record label Good Looking Records are most associated with the jazzy, atmospheric side of drum and bass music. The name "LTJ Bukem" is a contraction of "El DJ Book 'em", a nod to the Spanish for "The DJ". "Book'em" (or "Book'em Danno") is the well-known catchphrase by Steve McGarret, Senior Officer to "Danny Williams" on the television series Hawaii Five-O. Together we get "Ltj Bukem".
