When it comes to performing, CBS radio has called him "the best live act you've never seen" and another writer for No Depression gives him the oddly flattering title "the best songwriter you're not listening to." Filmmaker Peter Harding was so moved by the underground nature of Stephen's story that he made a documentary called "Last Man Standing" which went on to become an Amazon exclusive film. “SK” as he is affectionately referred to by fans, has persisted in building a substantial career that has landed him onstage with some of the biggest and best touring bands in the world (Train, Sugarland, Jason Isbell, Sara Bareilles, Hanson and OAR to name a few.) Kellogg's music has found it's way onto the Billboard charts and been featured in numerous films and TV shows. His Americana-tinged, folk, pop and rock stylings can make his sound hard to define, but to his core this musician, storyteller and father of four brings heart and incredible energy to everything he does.
