Camilleri's work includes researching and writing the biography of Tony Carr, a Maltese musician with a remarkable career working with distinguished, world-renowned artists. For his research on jazz in Strait Street with focus on Tony Carr, Camilleri received the RIDT Charles Gatt Award. He wrote and produced three documentaries: Strait Street to Abbey Road, about Carr's life and career based on the same research; Mar-Ritmu tac-City, a short documentary about Charles Gatt; and Keeping Time: The Malta Jazz Festival Story. He is also the founder of Nix Mangiari, an independent cultural research platform and label, through which he initiated Anecdotes of Jazz in Malta, a project that combines live music with film.
