South African pianist Abdullah Ibrahim and Cameroonian saxophonist Manu Dibango will play Brecon jazz this summer, say organisers.
In a reduced programme there will be 25 concerts between 7 and 9 August, which will also feature free family events, fireworks and a jazz carnival parade.
The festival was in jeopardy four months ago when the company behind it went into liquidation.
Officials behind Hay Festival were chosen to run Brecon jazz in March.
There had been plans to postpone the festival in 2009 after the Arts Council of Wales, which was overseeing its future earlier this year, said to organise a successful event in just six months was "too big a hurdle to leap".
But it was eventually decided to hold a smaller, scaled down event.
Among other performers appearing this year is Tunisian oud player Anouar Brahem, and British saxophonist and clarinettist Courtney Pine.
The festival will be held in three central venues - Theatre Brycheiniog, an 800-seater concert venue and a 500-seater café venue - and Brecon Cathedral.
Jazz festival organiser Peter Florence said: "Brecon (will) be different this year, and very different next year.
"It's a huge adventure, and we're deeply grateful to everyone who's been so supportive and encouraging."
A full festival programme will be launched in mid-June.
Meanwhile, a Brecon Jazz Academy will be launched in August.
The festival celebrated its 25th anniversary in 2008.
But it ran into financial difficulties after poor weather hit ticket sales.
