Todd Rittmann is perhaps best known for his time in bludgeoning sludgecore act U.S. Maple; while his new project, Dead Rider, minimizes guitar in favor of angrily-shrieking electronics, the result is no less abrasive. Witness “Weird Summer.” Like a club hit from the Isle of Styx, the song heaves and kicks. Ghostly backing vocals drift in and dissolve, a weird razor-wall of digital noise bisects the song at the center, and Rittman’s deranged beat-poet delivers free-verse omens (“more towers going up now, now birds touch the ground…another neighbor disappears”) against queasy neon synths. It’s a bracing snapshot of a future that’s not just dystopic but violent — looters and punks kicking in abandoned cars between barrels of burning refuse, beneath a sky lit by LED billboards.
