Lumen Drones is a fascinating and powerful collaboration between Hardanger fiddle master Nils Oslashkland and Per Stainar Lie and Oslashrjan Haaland, respectively guitarist and drummer with the Norwegian 'post-rock' group the Low Frequency In Stereo. The participants describe their project as a psychedelic drone band, but its stylistic reach is broad and evocative and will trigger many musical associations.
