A militant UK reggae heavyweight from the late 1970s — this 12″ single delivers two extended roots-vocal explosiones: the haunting “Where Is Jah” featuring Allan Kingpin on vocals, and the dub-heavy “Black Star Liner” featuring Tony Benjamin. Mixed by the legendary Dennis “Blackbeard” Bovell, this release stands as a landmark in Greensleeves’ early catalogue and UK reggae history.
