For their new campaign Unite All Originals mega brand adidas invited hip-hop legends Run DMC and DJ talent A-trak to create the soundtrack for a very special interactive video experience that they launched earlier this month. Today they are taking it one step further with their new Drop a Rhyme challenge that let’s you become a part of the experience. For this A-trak created a beat sample for those of you who can master the art of rapping to drop their own rhymes ontop of it and record it with Instagram. Sounds like your kind of challenge? Than go and get into the groove with the beat. Oh, make sure not to forget to tag it with #unitealloriginals, #adidasoriginals and @adidas_de before you upload it. The best rhymes will not only win some cool adidas outfits but will also be edited into one final, global music video that will be released in the end of September. To inspire you, starting Monday a few popular artists will publish their rhymes for you on a daily basis, among them Lary, MC Fitti, Weekend, Teesy and DJ Kitsune. Find our more and take part in the Drop a Rhyme challenge here. An instructional video on how to take part also after the jump.
