Like tourmates Deafheaven, Russian Circles are a metal-based band whose music is also spacious, lush, and atmospheric; like fellow Chicagoans Pelican, Russian Circles are purely instrumental, with no vocalist or even central element on which to focus. Frequently, then, the power trio’s music feels closer to post-rock than it does metal. Russian Circles’ forthcoming fifth LP, Memorial, will feature vox on one song — the album closer (and title track), on which the similarly metal-adjacent Chelsea Wolfe guests — but its initial premiere, “Deficit,” is wordless and voiceless; its emotion and direction are derived entirely from the flowing mass of sound. Listen.

Memorial is out 10/29 via Sargent House.
