IDeftones’ ninth album reaches for a plane beyond loud and quiet, where the band is free to indulge its harshest and most gentle impulses at once. For the first time, they make it look easy. Ohms reaches for a plane beyond the simple loud vs. quiet dichotomy, where the band is free to indulge its harshest and most gentle impulses all at once. On Ohms, they keep their most adventurous sounds to the margins. “Pompeji” dissolves into a wash of ominous synth drone, lulling you into complacency before the hydraulic rhythms of “This Link Is Dead” arrive to shake you awake; “The Spell of Mathematics” spends half its runtime on a gorgeous instrumental coda, with placid guitar chords draped like a security blanket over anxiously shuffling drums.
