Terry Crews, the somewhat lesser known but infinitely louder and more muscle-y Old Spice guy, is back with a raucous new project for the men's care brand—Old Spice Muscle Music. In the Vimeo video below, Terry's muscles are all hooked up to musical devices—snare drums, bass drums, tom-toms, tambourines, guitar, bike horn, woodblock, even a "flame sax" set of three saxophones. When he flexes each muscle, an instrument plays—flex them all furiously, and you get a symphony of muscle-y sound. The video is just one piece—when it finishes, you can use your keyboard to play, and even record, some special Muscle Music of your own. The campaign is a collaboration between Old Spice, Wieden + Kennedy, director Tom Kuntz of MJZ, editing house Mackenzie Cutler, effects specialists The Mill and Vimeo. Credits after the jump.
