Principles of Geometry, the French duo of Guillaume Grosso and Jeremy Duval, have created one of the more generally insane releases of late in the Tigersushi family. Synth fetish music made by Aphex Twin-obsessed forest creatures, Lazare giddily chases around moods and ideas with no discernable end in sight. A snarly Cannibal Ox drops in on a float-along synth track (“Napoleon”) and gets spit out at the other end of Black Strobe’s studio, while tracks like “Titan” and “Shaber Hill” set up delirious cat’s cradles of analog-synth tones. The album’s gem, “A Mountain for President,” with the bonus of Sebastien Tellier’s voice, is alone worth the price.
