As the title suggests, those obsessions include his fascination with the musical device of the drone. This was something Jóhannsson felt as a visceral presence, “a fundamental vibration that anchors music and gives you a foundation”. He often used both acoustic and electronic drones – sometimes gently underpinning the music, sometimes drowning out everything else. The new meaning the word has acquired in modern times gave it additional layers of resonance for him. Here, his drones have a motivic-like role, shifting and shimmering with hypnotic effect, conjuring different moods, from unsettling to uplifting, as the work progresses.
