As one of contemporary rap’s most in-demand mix engineers, Patrizio "Teezio" Pigliapoco distinguished himself in the early 2020s by sculpting No. 1 hits for Jack Harlow and racking up cowriting credits with Chris Brown. Since engineering for Juicy J as a teenager, the Los Angeles native has built lasting relationships with many of hip-hop’s commercial juggernauts—Lil Nas X, Gunna, Polo G—by demonstrating that mixing is a vibrant and creative art that can make or break potential hit records.
