Oh, let’s bring it, strut, shuffle and all with a new campaign from Saatchi & Saatchi London, which gives us the “James Brown Challenge.” The goal of the agency’s rather formidable effort is to meld filmmaking and music while also celebrating the man that serenaded Apollo Creed in Rocky IV. Damn you, Drago. For those interested, you have four tracks from the godfather of soul to choose from, create a full-length video around it and June 25 to complete it. Saatchi is no stranger to the music mashup game, as we call recall the agency’s efforts to promote Moby last year.
