So here’s a strange symmetry: Dylan Carlson’s Earth began life 20 years ago as a sludgy, epically slow-riffing doom metal band but has in recent years explored a more acoustic landscapes of twanging desert drones. Meanwhile, Mount Eerie’s Phil Elverum got his start making spaciously layered songs on acoustic guitar and drums as the Microphones but has lately honed his “black wooden” sound, adding shuddering waves of electric guitar distortion and noise to his still gentle singing. At some point in the past decade, you can imagine them playing the exact same thing, their paths perfectly crossing before they continued on in their opposite directions. Earth’s latest, Angels of Darkness, Demons of Light I (a sequel is expected next year), continues in their current vein, dour but clean, adding the prolific Lori Goldston on cello and frequent Elverum collaborator and distinguished solo artist Karl Blau on bass. With Mount Eerie, Low Hums. ERIC GRANDY
