“I’ve been working with Bill since 2007 and he’s consistently my top-call guitarist.  Aside from his sheer talent as a musician, he is extremely professional and easy to work with.  As a fellow musician and teacher, I would recommend William Seiji Marsh without any reservation!”

keyboardist for Mike Posner, BANKS, KD Lang


“Bill Marsh is a phenomenally talented player and singer.  Technical ability aside, Bill’s true power comes from the fact that he is a deeply musical person.  He can see many sides of a song and can quickly intuit what the arrangement wants to become and then instantly communicate it with sublime clarity.  And while all of that is happening, he’s lightening the room with his easy going nature. Somehow he pulls off being a genuinely nice guy while being an absolute pro.”
