Arca is an experimental project by Alejandra Ghersi, a Venezuelan electronic producer, mixing engineer and DJ. Arca does not take many categories for granted. Her fondness for what she calls “in-between states” extends to gender, genre, emotion, and form itself. Mutability and ambivalence guide the sound of her music — the atmospheres she creates often contain abrasive percussive blasts, metal-shop whine, the screech of subway brakes, the whine of jet engines overheating. Anthropomorphic and animalistic sounds abound —mewling cats, mooing cows, anguished screams, the grunts and groans of orgasm, commingling pleasure and terror and beauty and ugliness in the most thrilling ways possible.

She's also been credited for her writing/producing efforts on Björk's Vulnicura and Utopia, FKA Twigs' EP2 as well as for her collaborations with Dean Blunt, Mica Levi and Kelela among others.
