Indie duo Billy & Bella layer influences of folk-rock and dream-pop with lush songwriting to create a sound reminiscent of pre-Millennial California neo-psychedelia. They combine elements from diverse musical interests, ranging from the folk and alternative rock of Mazzy Star, Chris Isaak, Radiohead, and Jeff Buckley, to harder rock influences of The Stone Temple Pilots, Carlos Santana, and Led Zeppelin, to create a contemporary take on the alternative rock and dream-pop sound of the late 1990s. Both former California natives, the imagery of the state appears throughout their songwriting to symbolize varying aspects of the human condition that span the range of nostalgia, reality, and dreams.
