Plasma marks a major shift for the band—away from the sonically “immersive” and towards an almost tactile, physical quality of sound: the type that is associated with functional electronica. This is also Ikarus at their most affecting, playful, and fluent. The record, like that stuff lighting up a rural sky, is an energy. It’s something awe-inspiring, both familiar and alien. It’s also five instrumentalists who figured out how to maintain their individual voices while becoming one: a seamless, highly malleable substance.
