The name of Norwegian quartet Krise translates as “Crisis,” and the title of its debut LP, Svartsymra, could be rendered as “Black Spring Flower.” But while Krise’s moniker sounds dire, its music does not. This may be due in part to bandleader/composer Kristian Enkerud Lien’s focus on alternate tunings and, particularly, just intonation. His guitars and Anna Ueland’s synthesizer are both tuned using systems that generate a resonant shimmer around the sounded notes.
