ドラムンベース
The phrase "drum and bass" was sometimes used in the seventies to name dub versions of reggae songs. With titles on b-sides of 7 inches, like 'Drum and bass by King Tubby's'. Also you can hear the phrase in reggae songs from artists like Jah Tomas with the often sampled phrase 'strictly drum and bass make you wind up your waist'. Or in album titles, like 'Show Case (In a Roots Radics Drum and Bass)' from Tristan Palmer.
