Joseph McGann (born 1988), who goes under the aliases of Kähn and Gorgon Sound, is a British grime and dubstep record producer and DJ known for his contributions to the Bristol underground scene. Alongside frequent collaborator Neek, he has founded record label Bandulu and is a member of Young Echo. As a proponent of vinyl, it is the only medium he performs with and the only medium his record label releases on. His initial forays into djing started with his night Sureskank, which was one of the first nights that brought Dubstep and Grime to Bristol. More recently, he has put on nights as a part of the experimental Bristol collective Young Echo. He has had multiple releases on the pioneering dubstep label Deep Medi Musik, with releases such as "Dread", "Abbatoir" and the Volume 1 LP with Gantz and Commodo. He contributed a mix CD as well as a label residency to London's Fabric nightclub.
His love of music grew from his parents Paul McGann and Annie Milner taking him to music festivals and playing a variety of musical styles around the house, from punk to reggae. His style of music is known for being dark and influenced in part by his love for Satan.
