[5] Having been trained on ragtime and swing, Laurance first began playing jazz at the age of 14 when he became the resident performer for a small restaurant in the Soho district on the West End of London.

[6][7] During his tenure at Leeds, Laurance met traveling University of North Texas jazz student Michael League, the two going on to perform a number of shows together in the UK.

[10] His debut feature film score was for Un Traductor (2018),[11] an independent drama by directing brothers Sebastián and Rodrigo Barriuso which was named as Cuba's official entry for the 92nd Academy Awards.

"[20] In November 2018, Laurance collaborated with the WDR Big Band of Cologne, performing concerts at Kölner Philharmonie[21] and Southbank's Queen Elizabeth Hall[22] in London.

[23] As a member of Snarky Puppy, Laurance has collaborated with a number of artists and groups, including the Metropole Orkest, with whom the band won a GRAMMY award for the 2016 album, Sylva.

2 albums, Laurance collaborated with artists including Lalah Hathaway (whom he also accompanied at the GroundUP Music Festival in 2019[25]), Salif Keita, Susana Baca, Laura Mvula and Jacob Collier.

In 2019, while touring in Berlin, Germany, to promote his studio album Cables, Laurance played a completely improvisational piano piece channeling the emotions elicited by the UK electorate's decision to officially withdraw from the European Union (EU), commonly referred to as Brexit.

Laurance described the decision to leave the EU and the ensuing political events as "total madness and chaos", stating "It's devastating, the prospect, that [he] as a British person wouldn't be part of Europe."
