From Sarah Brand’s own Website:

ABOUT ME
I am a music video director and singer-songwriter from Malibu, California. I write primarily pop music infused with sociological introspection spanning topics such as religious hypocrisy, inequality, and romance. I write all my music, as well as direct and edit music videos. I am currently living abroad in England for a Master of Science in Sociology at the University of Oxford. I received my B.A. in Sociology from UC Berkeley, with Highest Honors, and a minor in History.
