As proven on their strange and beautiful new album Mudglimmer, the looming specter of artistic oblivion pushed The Slaps to lean into their idiosyncrasies: snaking rhythms, complicatedly interlocking guitar riffs, grubby yet alluring poetry, and homespun post-modern Americana sing-alongs all surge with a free-wheeling improvisatory verve informed by free jazz. It’s a stunning DIY comeback story, a doubling-down on avant-garde impulses that pays immediate dividends. Spontaneous composition and earnest, threadbare folk collide on Mudglimmer. It’s a marvel of influential synthesis, evoking Slint’s comfortability with ominous tension (“Mudglimmer”), Tortoise’s slinky push-pull grooves (“Filthy Sex Manuevers”), Waxahatchee’s slice-of-life Americana gems (“Flip”), elliptical funk-punk a la The Minutemen (“Forward”), minimal grunge-pop in the vein of Sebadoh (“King”) and so much more. Mudglimmer, in short, rips. Faced with existential threats, The Slaps reconfigured and reenergized — finding purpose, not in reaching for a brass ring, but in becoming fully, unashamedly, their own wonderfully confounding thing.
