Fatboy Slim has confirmed that Martha Wainwright and Cyndi Lauper will appear on the album he worked on with former Talking Heads frontman David Byrne.
Here Lies Love is a concept record about the life of Imelda Marcos, the former first lady of the Philippines.
"Each track is sung by a different singer and there's some very interesting guests on there," said the DJ, whose real name is Norman Cook.
He said the album is expected to be released in the next six months.
The pair finished the writing process about two years ago and, speaking to BBC 6 Music, Cook explained why progress was slow.
"David's been trying to get the stage show together, because the idea was that it would be the antithesis of Evita, but then we couldn't find our lead, so we didn't know who was going to sing it."
"I was trying to persuade David to sing it," admitted Cook, but in the end, he added, the pair decided to recruit more than 20 guest vocalists instead.
He remained tight-lipped as to the cast but confirmed Cyndi Lauper and Martha Wainwright were "involved somewhere along the line."
In a recent interview, Byrne said soul singer Sharon Jones and soundclash star Santigold had taken part. Tori Amos and Candie Payne are also rumoured to have been involved.
'Dance music based'
Cook said the sound of the album was not hugely experimental, unlike Byrne's 1981 collaboration with Brian Eno, My Life In The Bush Of Ghosts.
He said: "It's a story-telling thing, like Evita, but coming at it from a different angle in that it tells the untold story that people didn't know about Imelda Marcos. It's not just about the shoes.
"Musically, because it's David Byrne, it's not going to be straight up 'Tomorrow, tomorrow, I love ya, tomorrow...'"
However, Cook revealed the album would in part be inspired by dance music.
"The story is more about what was going on in Studio 54 than what went on in the Philippines. We wanted to reflect that, so it's kind of dance music based," he said.
Meanwhile, Cook revealed he was back in the studio working on a new solo album.
He said progress was "not far" along - and could be delayed by the arrival of his second son with presenter Zoe Ball next February.
