Italo Deviance is the moniker of Marcello Giordani, an Italian DJ, producer, and collector who started his career in the 1990s. He became known for his extensive collection of rare Italo Disco vinyl, which led him to create the "Italo Deviance" blog in 2008 to promote obscure tracks from the 1980s. Giordani was also part of the duo Marvin & Guy from 2011 to 2023 and is the founder of the Italo Deviance Music label.
