On stage, his improvisational style of playing echoes that journey, invoking deep emotions and producing just the right sound that is easy on the ear, yet powerful in delivery. Each performance is orchestrally crafted, emboldened with rich and unconventional harmony. Ralston has clearly been inspired by Classical masters, Sergei Rachmaninov, Frederick Chopin and Alexander Scriabin, and Jazz greats, Keith Jarrett, Joe Sample and Oscar Peterson.

One of his career highlights came in December 2013 when he was invited to perform for Nelson Mandela's Memorial Service at the South African Consulate in Shanghai, China, where he played legendary pianist Abdullah Ibrahim's composition "Mannenberg" and other South African songs.

His debut EP "Red Lanterns" released in 2012 and subsequent Jazz and Christmas singles over the last 10 years, have been featured on South Africa's Zone Radio "Hill And Dale No Hoops Required" showcase. The track "Red Lanterns" has also been air-played on South Africa's FMR Radio "Night Beat" show in March 2021.

Raised in Cape Town, Ralston first took piano lessons from his father at age around 7. At age 10, he went on to pursue formal Classical training at the Battswood College of Music in 1986 through till 1994 with music teacher, Cheryl Wesso. During those 8 years he also enrolled in the Royal Schools of Music examinations through till grade 8, obtaining distinctions in his practical examinations. In 1995, he started Jazz studies with George Werner at the Jazz Workshop, after which he then pursued a business degree. In 2001, he resumed his Jazz studies at the Jazz Workshop with legendary Jazz pianist and teacher Mertyn Barrow.

Ralston performs both as a solo act, as well as in various ensembles and productions.
