Find the best Melanie Martinez - The Trilogy Tour concert tickets at 3Arena, Dublin. Melanie Martinez is one of those rare artists who really commits to a concept, shape-shifting and all. You probably know her best by the "Cry Baby" character that defined her early career; sporting half-pink hair, adorned in doll's dresses, maybe carrying a baby bottle. Check in on her now, and you'll see her as a grotesque four-eyed naked alien creature - part Labyrinth, part Bjork, all thrillingly weird. In the irreverent alt-pop that accompanies these alter-egos, she doesn't slack either; throughout her discography, she unwaveringly confronts taboos amid gleefully catchy hooks.
