David started singing when he was only six years old. He met Victoria De Angelis, Thomas Raggi and Ethan Torchio, his future band members from Måneskin, during high school days. He studied at the liceo linguistico Eugenio Montale in Rome, but he did not complete high school and instead devoted himself to his music career, for which he also had the support of his parents. When introduced for the position of a vocalist for their local band, he was initially rejected because his style was considered "too pop", but his insistence to be in the band eventually got him accepted. David soon changed his demeanor and style, especially his stage persona, because he learned how to freely express himself, as well as gaining confidence in his sexuality. The band was formed in 2016 and initially played as buskers in the streets of the city of Rome, but in 2017 they soon rose to prominence when they finished second in the eleventh season of the Italian talent show "X Factor". The band had a breakthrough debut with the studio album "Il ballo della vita" and tour in 2018 and 2019. In 2021, their second studio album "" was released.
