Arca was born in Caracas, Venezuela. Her father was an investment banker and her mother studied International Studies. Her family moved to Connecticut for a time, before returning to Venezuela, where she was privately educated and was introduced to piano lessons. She released music in her teen years by the name of Nuuro, and received moderate popularity in her home country, with praise from big national artists such as Los Amigos Invisibles. She later attended the Clive Davis Institute of Recorded Music at NYU.
