Scandinavian folk duo My Bubba make soft, soulful music that is as playful as it is powerful.     Together, My Larsdotter and Bubba Tomasdottir have toured with Damien Rice, co-written music with Matthew E. White, recorded with Noah Georgeson and stepped on Bryan Adams’ toes. Literally. My Bubba's new album is a personal and intimate collection of their favorite Swedish folk songs, which will be released on the duo's own label Cash Only on August 25th.
