Elverum’s monumental new Mount Eerie album Night Palace feels both like a third definitive rupture and a culmination of his work over the past 25 years. Night Palace embraces some of the biggest vistas and most sumptuous imagery of any album he’s ever made. At 46, he’s still trying to explain what the long song he’s been singing for his entire career really means. At 26 tracks just barely topping the capacity of a single CD, Night Palace is a double album by any definition, not least in the classic-rock sense, and the messy but truthful sprawl that implies. “Blurred World” is a vignette of contentment, set during a midnight piss, that lets a bit of MJ Lenderman’s shaggy-dog humor into Elverum’s universe.
