Marvin began singing at his local church kids choir at the age of 6. As he grew older, his voice became deeper. Reluctant at first to embrace his baritone voice, Marvin restarted his singing career at the age of 15, when he won first prize in a talent contest at his secondary school, Kingsford, where he did his first solo public performance of Frank Sinatra's rendition of Fly Me To The Moon. It would introduce Marvin to the world of vocal jazz and make him realise that he wanted a career in music. 

Marvin has come a very long way since then. At 18, he moved to Somerset to study an FdA in Popular Music and a BA Hons in Professional Music Performance and Production. Since graduating in 2017, Marvin appeared on The Voice UK and reached as far as the semi-final of Britain's Got Talent 2018 along with fellow 'Ratpacker', Dennis DeMille. He also made his musical theatre debut as the 'Ghost of Christmas Present' in the Alan Menken musical 'A Christmas Carol' which ran for 9 shows at the Weston Playhouse and the Theatre Royal in Windsor.

Marvin has many other strings to his bow.  He is also a self-taught trumpeter, composer, arranger and songwriter. Marvin's overall style is heavily influenced by the likes of singers such as Frank Sinatra, Nat King Cole, Billy Eckstine, Ella Fitzgerald, Billie Holliday, Sammy Davis Jr. and Tony Bennett and renowned bandleaders and arrangers such as Quincy Jones, Billy May, Nelson Riddle, Count Basie and Duke Ellington.

Marvin is also a published author. Heavily inspired by the illustrations of Dr. Seuss, he illustrated and wrote three picture books between the ages of 9 and 11. The books were entitled 'There Are No Such Things As Dragons', 'Hopper Holiday' and 'Peter Hopper and The Caveman Chaos'.
