Over the last decade Massachusetts songwriter Stephen Kellogg has performed more than 1500 concerts in more than a dozen countries, both solo and with a band. In 2013 he gave a TEDx Talk about job satisfaction. Recently on a tour of Europe, SK (as fans often referto him) made a detour to play the Middle East, Africa and an aircraft carrier for the Armed Forces. Upon returning to the USA, he started his annual lyric writing campaign to raise money and awareness in the fight against pediatric cancer. At first glance none of this has anything to do with his music, but Stephen Kellogg would argue, “it is the whole story. The music I make is a reflection of how I spend my time and what I care deeply about.” His Americana-tinged, sometimes folk, often rock, occasionally pop stylings can make Kellogg hard to define, and his most recent four-part album “South, West, North, East” embraces the notion of genre-splitting to the fullest.
