The distinctive voices of three Welsh stars - Connie Fisher, Cerys Matthews and Bryn Terfel - will all be heard at this year's National Eisteddfod.
Famous voices: Cerys Matthews, Connie Fisher and Bryn Terfel
West End star Fisher, former Catatonia front woman Matthews, and opera singer Terfel will perform at the highlight of the Welsh cultural year in Cardiff.
The two women will perform in a special night entitled C Ffactor on 7 August.
Meanwhile, Terfel will sing Verdi's Requiem with German soprano Anja Harteros on 4 August.
Fisher, who grew up in Pembrokeshire, found fame when she won the BBC competition to find a star for a new stage production of The Sound of Music.
Last weekend she donned a habit to play Maria in The Sound of Music for the final time, said she wanted to "come back and say thanks " to Wales.
She and the I'm a Celebrity... Get Me Out of Here star will be joined by harpist Catrin Finch and fellow singers Shan Cothi and Caryl Parry-Jones for their night of musical collaboration in a 3,500-seat pavilion.
Fisher, who is from Haverfordwest and who was picked for instant stardom in the BBC series How Do You Solve a Problem Like Maria?, said she started off competing musically in eisteddfodau as a girl.
'Make them great'
"I will be performing a set full of Welsh numbers and I am thrilled that I will be sharing a stage with Cerys. She is a real Welsh legend - I think she's brilliant."
It was recently announced that a planned UK concert tour in the spring following her departure from the West End stage had been called off
She said: "My concerts have been postponed and not cancelled. We wanted to get the album out first.
"We wanted to do few things but make them great."
Matthews, meanwhile, has just ended her Welsh tour after her appearance on ITV's jungle celebrity eviction show.
Cerys Matthews spent several weeks in the Australian jungle last autumn
The former lead singer of Catatonia has attracted a huge amount of publicity following her relationship begun in the Australian jungle with former Eastenders actor Marc Bannerman.
Earlier last year she returned to west Wales with her two young children after divorcing her American husband.
Eisteddfod chief executive Elfed Roberts said the C Ffactor (the double "f" following the Welsh spelling) which follows the would be exciting and a "different night for the eisteddfod".
"Both have been big supporters of the eisteddfod and we are hoping that they will help to show that the festival can offer something for every taste."
Meanwhile, Terfel will lead a performance of Verdi's Requiem in Latin with conductor Daniel Harding, German soprano Anja Harteros - who won the Cardiff Singer of the World in 1988 - and others still to be confirmed.
They will be accompanied by the BBC's National Orchestra of Wales and National Chorus of Wales.
