Marcus was awarded a distinction in AMEB Diploma A.Mus.A for Music Performance and Theory and passed Seventh Grade Musicianship with honours, all by the age of seventeen. In his final years of high school his passion for electronic music composition and sound engineering inspired him to establish a recording studio at his college.

After graduation, Marcus embarked on a career of sound engineering and performing music in Sydney and the northern coast of NSW, Australia. In 1996 he commenced recording sound for the major Australian networks and emerged as a supplier of sound design, music composition and audio post production for television content.

To satisfy demand, Marcus launched Full Circle Audio as a niche sound design company in 2006. After two successful years of operation, he relocated the studio from Artarmon to its current premises in Bourke St, Redfern.

Marcus’ sound design and music has delighted audiences at Sydney’s Vivid Festival, White Night Melbourne, the Brisbane Festival, the Hong Kong Pulse Sound and Light Show, and festivals in Singapore and Macau. His work also features in scores of brand releases and product launches from Tokyo and Shanghai, to Los Angeles, Detroit, Geneva, Frankfurt, Paris and New York. Marcus’ recent voice production work includes bestselling audiobooks and industry-leading podcast series. To date, Marcus’ work has been featured on hundreds of broadcast programs in Australia and around the world.

Marcus is also musical director and co-composer with the highly acclaimed Indigenous Australian artist Radical Son, and appears regularly as part of their performances at many of the country’s major music festivals and concert halls. In 2024, their latest album “Bilambiyal” was nominated for an ARIA in the Best World Music Album category.
