Describing his sixth studio album Yeezus (2013) as "a protest to music," West embraced an abrasive style that incorporated industrial music, acid house, dancehall, punk, electro, and Chicago drill. Inspired by the minimalist design of Le Corbusier and primarily electronic in nature, the album features distorted drum machines and "synthesizers that sound like they're malfunctioning, low-resolution samplers that add a pixelated digital aura to the most analog sounds." To this end, the album incorporates glitches reminiscent of CD skips or corrupted MP3's, and Auto-Tuned vocals are modulated to a point in which they are difficult to decipher. It also continues West's practice of eclectic samples: he employs a sample of Nina Simone's "Strange Fruit," an obscure Hindi sample on "I Am a God", and a sample of 1970s Hungarian rock group Omega on "New Slaves". "On Sight" interpolates a melody from "Sermon (He'll Give Us What We Really Need)" by the Holy Name of Mary Choral Family. Rolling Stone called the album a "brilliant, obsessive-compulsive career auto-correct".
