Opium Hum aka Michail Stangl – CTM co-curator, one of the people behind Boiler Room Berlin, co-organiser of the Leisure System parties and label, and all round progressive force on the Berlin club scene – nourishes his DJ sets on sombre, hazy drones and fantastical soundscapes permeated by deep and shifting rhythms to create what can only be called a wide-awake dream.
