Irons, a former vocalist turned manager and producer, and her partner Crosby also initiated the Dune Records label, drawing on talent from Tomorrow's Warriors, including such graduates of the organisation as Denys Baptiste, J-Life and Soweto Kinch.

[6][8] Tomorrow's Warriors partners with venues, promoters and organisations across the UK to develop audience participation in jazz, with regular live public events.

"[10] Since its inception by Gary Crosby and Janine Irons in 1991, Tomorrow's Warriors has worked towards devising and producing inspirational programmes and performance opportunities for new and emerging musicians, at the same time as developing culturally diverse audiences, being considered to have "nurtured many of the UK's leading jazz performers via its award-winning jazz education and emerging artists programme" with Tomorrow's Warriors alumni winning more than 50 awards and achieving successful careers in the music industry.

[4] The Tomorrow's Warriors' programme provides a wide variety of opportunities ranging from workshops and showcases for young musicians to concerts and tours for established professional bands and orchestras, partnering with a network of local, national and international arts organisations, as well as commercial producers, venues, promoters and festivals.

[4] Trustees of Tomorrow's Warriors include Steve Abbott, Viv Broughton, Margaret Busby, Peter Comber, Nick Cornforth, Camilla George, Nicky O'Donnell and Chris Panayi.

In 2008, Tomorrow's Warriors established an orchestra initially to provide a platform for pianist/composer Peter Edwards – who was a participant in the young artist development programme[20] – to recreate Duke Ellington's rarely performed The Queen's Suite.

[24] Other major projects undertaken by the NCO include in 2013 a 50th-anniversary recreation of Charles Mingus's The Black Saint and the Sinner Lady (1963) at the Purcell Room,[25] about which London Jazz News wrote: "The ensemble was flawless.

"[33] On 15 September 2023, at the Royal Festival Hall, a 32-piece all-string version of the NCO with saxophonist Nubya Garcia, an alumna of Tomorrow's Warriors, performed their exploration of Stan Getz's 1962 album Focus, together with two new works by Black British composers Oleta Haffner and the NCO's Peter Edwards – in a well-reviewed concert,[34][35][36][37] described as "instantly setting a new standard for the creative use of a string orchestra in jazz ... in a performance that mixed care and joy in admirable proportion.

Even greater, maybe, given that each musician in the sprawling QEH line-up had a common denominator, and was fundraising for the same cause: Tomorrow’s Warriors, the pioneering jazz music development charity celebrating its 30th anniversary year.

"[58] At the Brit Awards 2025, the Ezra Collective went on to further acclaim, becoming the first jazz band to win "Group of the Year", with frontman Koleoso again acknowledging the importance of their early opportunities through Tomorrow's Warriors and the need to sustain funding for such youth music education initiatives.
