While most think of Isaiah Mustafa on a horse when they think of the Old Spice guy, Terry Crews was there earlier on, flexing his pecks and yelling a lot. And he's back for more with a brilliant—and suitably surreal—interactive Vimeo clip made by Wieden + Kennedy called 'muscle music', where different instruments—including a "flame sax"—are played through Crews' rather rhythmical flexing. Pfff, V Motion Project. But wait. There's more. After the vid is finished users can perform and record their own song with the keyboard.
