At times a cello (electrified?) performs the role of programmed synthesizer for the obbligato tenor repetitive pattern in a kind of electro-acoustic mashup that is quite odd. Don't think I've heard that before. As usual with Swedish music some folk importations appear here and there like virtual particles bubbling out of the quantum foam.
