Here's a piece I wrote for Pitchfork about 20 years of Auto-Tune - and the whole related realm of pitch-correction and "vocal design" technologies. It spans from from Cher's "Believe" to Migos's "Slippery," via Britney, Kanye, Ke$ha, Keef, Flavour N'abania, Man like Nayvadius, and more. Detractors dispatched; digital existence dissected; defining sound of the 21st Century delineated.
