Ethan here. I’m Ethan "Ertez" Martinez, 20. Music is my life—I got my first guitar at 15 and haven’t stopped since. My father’s a famous Spanish musician, my mom an Italian singer. I play in a boys’ band and pour everything into our music. I met her at 19, and we’ve been together ever since. On stage, my band calls me "Ertez," my raw, untamed musical side.
