The Monks were a short-lived rock band launched in the mid-60s by five army vets in Germany. They began as a run-of-the-mill combo, but an encounter with two German admen transformed them into concept-rock mimimalists who wore black robes and matching tonsures and whose sole album, Black Monk Time, presaged the rise of heavy metal and punk. This absorbing video documentary by Dietmar Post and Lucía Palacios tells the Monks' story with precision and flair, climaxing with a 1999 reunion gig in New York. But it's the witty and unsentimental interviews with the five band members that reveal their focus and idiosyncratic brilliance. 100 min.
