Marina and The Diamonds is the stage name of Marina Diamandis, a Welsh singer/songwriter who makes vibrant, electrified indie pop. Her debut, 2010's The Family Jewels, showcased her theatrical approach to pop songcraft, with songs like "I Am Not a Robot" and "Oh No!" merging big hooks with kitschy synth arrangements. Its followup, Electra Heart, refined this formula, debuting at No. 1 and featuring singles "Primadonna" and "How to Be a Heartbreaker." Much like her music, Diamandis is known for her flamboyant fashion sense and quirky sense of humor.
