Marshall's 2013 album Spirit Speech - ‘an excellent, imaginative and distinctive album that repays repeated listens’ (LondonJazzNews) led him to be unanimously selected by Jamie Cullum, Gilles Peterson and Jez Nelson to perform at BBC Introduces, Manchester Jazz Festival that year. Meadowsweet is his latest creation, fusing influences from Bill Evans to Aphex Twin to Steve Lacy to Debussy.

In 2015 Dominic became the pianist for British nu-jazz group The Cinematic Orchestra, with whom he has performed all over the world including at Montreux Jazz Festival, Glastonbury Festival, Tokyo SummerSonic, Brixton Academy, Royal Festival Hall and LA’s Walt Disney Concert Hall.

Dominic's hip-hop covers album Cave Art was one of KMHD’s top 10 jazz albums of 2015. UK Vibe called 2016's The Triolithic "a very entertaining and refreshingly original album that is worthy of high praise." 2017’s beat-tape Silence’s Garden sold out quickly on Acorn Tapes, Bringing Down The Band reflecting "These tracks have a great vintage texture, and a whole lot of bounce". Cave Art volume 2 sold out in 2 days and was played on radio by DJ Househoes & J-Rocc.

It was Compassion Fruit, Dominic’s first vinyl release as a solo artist, that “exhibited his talents as a producer and multi-instrumentalist so well you’d think he’s been in the game for a decade with 5 albums behind him” (In Search of Media).

Since graduating from Amsterdam Conservatoire in 2012, Dominic has performed with Miguel Atwood-Ferguson, Jules Buckley & the Heritage Orchestra, Deva Mahal, Tawiah and Dorian Concept. He also co-wrote 'Lessons' with Cinematic Orchestra, one of the hits from their acclaimed new album To Believe.

In 2020 Dominic released Nomad’s Land on Darker Than Wax - "a wonderfully crafted album from a gifted artist whose talents shine"; "great late night ‘future jazz’ to take you into the wee hours" (Backseat Mafia).

His new album Skeleton Keys was featured in Wordplay Magazine and track 07, ‘Mermaid’, has already been played on BBC Radio 2’s The Jazz Show with Jamie Cullum and selected as track of the week on Jazz FM’s Late Night China Moses.
