Organisers of the Brecon Jazz Festival have announced the full line-up for the event in August.
Lucie Silvas will be joined by other stars like KT Tunstall and Jools Holland
The wide-ranging field includes three performers not associated with jazz - Scottish singer-songwriter KT Tunstall, Lucie Silvans and classical singer Katherine Jenkins.
Several acts will also pay tribute to jazz legend Charlie Parker, to mark the 50th anniversary of his death.
Jools Holland is already confirmed for the festival, now into its 22nd year.
Two of the event's brightest stars will be Silvas and Tunstall, but they are not associated with the jazz scene.
Lee Collins, festival marketing manager, said "The jazz festival supports live music and young singer-songwriters and both Lucie and KT fall into this category.
"Although they are not associated with jazz, they have talent and write their own music."
Tunstall will perform on 11 August at Brecon Market Hall, while Silvas will perform the following day at the Watton Marquee, as will Jools Holland.
Tunstall's album, Eye To The Telescope, is in the UK's top 10 and has sold more than 200,000 copies. She is also set to feature at next month's Glastonbury Festival.
Mr Collins added that alto sax bebop legend Parker, who died aged 34 in 1955, would be remembered at this year's festival.
"The Dizzie Gillespie Alumni Big Band, the Count Basie Orchestra and the Charlie Parker Legacy Band with John Faddis will all pay tribute".
KT Tunstall will perform on 11 August
The three-day festival opens with a gala concert on the evening of 11 August, with Katherine Jenkins.
The Neath-born classical singer will perform with the National Chamber Orchestra of Wales in the festival's Watton Marquee.
The mezzo-soprano is the latest big name from outside the world of jazz to perform at the gala opening.
In previous years, Van Morrison, blues legend Buddy Guy and Welsh rockers Super Furry Animals have entertained the crowds.
Andy Eagle, the festival's director, said: "In the year that Wales won the Six Nations rugby grand slam, we couldn't think of a better act to help us celebrate the start of one of the most exciting arts events in Wales".
Among other acts confirmed are Georgie Fame, Human Chain, the Esbjorn Svenson Trio (EST) and the Tord Gustavesen Trio.
About 70,000 revellers regularly attend the festival which has an international following.
