Phil Elverum didn’t just spend two solitary years turning an aged, de-sanctified church in Washington state into his recording studio: He built himself a hollow, hallowed aesthetic to go with it. The proof is in Mount Eerie’s two self-released albums this year, Clear Moon and Ocean Roar. While the former is a spacey, dreamlike work dedicated to all things homey, the latter — just out this month — is a slow, nightmarish album about being cast aside, physically and spiritually, that references doom metal and cheap Krautrock while providing a framework for Elverum’s tender, trembling vocals. Opening for Mount Eerie is Philly’s Far Out Fangtooth, the toast of latter-day Siltbreeze label noise and haze.
