Marina Diamandis
Who: Marina Lambrini Diamandis is a Welsh singer and songwriter. She is known professionally as Marina and the Diamonds.

Why she's fearless: Marina straddles and blurs the lines between genres like synth pop and electro pop in her music — and makes it look easy while doing so. She's described herself as "an indie artist with pop goals," is a fearlessly unconventional dresser, and often analyzes fascinating components of human behavior in her music.

Our musical picks: "Primadonna" and "How To Be A Heartbreaker"
