The 55-year-old pop superstar moved away from her musical roots back in 1995 to put together an alternative record but it was never released and the singer has now admitted she's "mad" it's been buried for so many years.
During an appearance on 'Las Culturistas' podcast, host Matt Rogers asked the singer: "Can you drop that grunge album?" and Mariah replied: "I know, right? I'm so mad that I haven't done that yet ... but who do I drop it with?"
Rogers then suggested she should release it independently using "Garage Band or something, like, a grungy thing" and the singer added: "I could do that."
She went on to say: "It's a good album. OK, you will hear it. I was getting life from that, seriously. It was jokes, as well. They're everlasting."
Mariah previously opened up about the buried album in an interview with Zane Lowe on Apple Music 1 in 2020 revealing music executives banned her from releasing it.
She said: "I got kind of in trouble for making this album - the alternative albu - because back then, everything was super-controlled by the powers that be.
"I never really was like, 'Oh, we're going to release it.' But then I was like, I should release it. I should do it under an alias. Let people discover it and whatever, but that got squashed."
The album -titled 'Somebody's Ugly Daughter' - did get a release under the band name Chick with Mariah's pal Clarissa Dane taking over lead vocals. Mariah's singing was heard only as backing vocals and she was credited as D. Sue.
However, the original recordings with Mariah singing lead are believed to still exist.
The singer opened up about the project in her 2020 memoir 'The Meaning of Mariah Carey', writing: "I was playing with the style of the breezy-grunge, punk-light white female singers who were popular at the time.
"You know the ones who seemed to be so carefree with their feelings and their image. They could be angry, angsty, and messy, with old shoes, wrinkled slips, and unruly eyebrows, while every move I made was so calculated and manicured.
"I wanted to break free, let loose, and express my misery - but I also wanted to laugh."
Brian May has hailed The Last Dinner Party as "new British rock royalty".
The Queen guitarist attended the 'Nothing Matters' hitmakers' show at London's Eventim Apollo on Wednesday night (16.10.24) following an invite from lead guitarist Emily Roberts.
Brian admitted the group - also made up of Abigail Morris, Lizzie Mayland, Georgia Davies, and Aurora Nishevci - "completely smashed it" at the show.
He wrote on Instagram: "I got to meet the new British Rock Royalty tonight - The Last Dinner Party - and they completely smashed it tonight at the Eventim Apollo. What a great show ! What a joy !!! Thanks Emily for inviting me. (sic)"
Brian also admitted the gig provided him with a "good old dose of rock tonic", which was exactly what he "needed".
He wrote: "That was just what I needed - a good ol' dose of Rock Tonic. Folks, you have to see these guys. Bri (sic)"
It comes after The Last Dinner Party had to axe shows in Lincoln and Cardiff last month "due to a sudden illness within the band", and they then cancelled four more tour dates - in Birmingham, Nottingham, Bristol, and Southampton, which were due to take place on October 1st, 2nd, 4th and 5th respectively - due to "unforeseen illness".
A post on the band's official X page at the time read: "It is with heavy hearts that we announce the difficult decision to cancel our upcoming headline tour dates in Birmingham, Nottingham, Bristol, and Southampton.
This is due to an unforeseen illness in the band and, following medical advice, we have to prioritise our health at this time.
"We are devastated not to be sharing these nights with you, and to have missed the shows in Lincoln and Cardiff. You should all know you've made this the most wonderful year of our lives and we can't thank you enough for your love and support. Truly."
