A decade ago, so-called “glitch” techno was a call to arms against synthesizer presets and cliché dance rhythms. Yet such subversion quickly gave way to convention, and in many sad cases, after-dinner comfort. Michael Santos’ aptly titled The Happy Error embodies the latter. The opening title track sets the album’s floatation-tank atmosphere, where the “glitches” are mere bits of static that bathe aquatic synth drones. “Swing Deluxe” sounds like a Mouse on Mars b-side from ’97, as Santos releases bubbly synth pops and yelping electric feedback. But just when it’s time to doze off, tension finally arrives on “Upper Cosh,” where his static noises overload into busted-TV-like dissonance.
