With the twitchy triplet rhythms of his hi-hat programming, Tim “Timbaland” Mosley changed the sound of rap and R&B. And in doing so, he helped build the careers of Missy Elliott and Ginuwine on shimmying, bawdy tracks like “Work It” and “My Pony”, respectively. Over the decades, he continued evolving his eccentric sound on funky, densely textured hits like JAY Z's unruffled “Dirt Off Your Shoulder” and Justin Timberlake's seductive “SexyBack”.
