Rhett was born and raised in Finchley, North London to parents of Irish and Italian American heritage. His parents met in New York while his mum worked for Sire records and his dad worked as a tour manager for the likes of The Ramones and Blondie. Growing up he went to school at the London Oratory in Fulham, while travelling across London daily further exposed him to the sub-cultures of graffiti and skating.
His first musical steps were through a metal cover band, playing tribute to Black Sabbath and Motley Crue, which later transformed into a punk band. Adding his later influences like Terry Reid, Shlomo and Roll Deep to the mix, Rhett formed his current angle on the music he makes today.
