In celebration of the 30th anniversary of her self-titled debut — which came out June 12, 1990 — the octave-leaping diva is taking it back with her #MC30 Friday series that kicked off on Friday.

Fittingly, the Long Island-born singer revealed footage of an early showcase at New York’s now-defunct Club Tatou in 1990. With her curls in full effect, wearing a crushed-velvet minidress, Mimi left no doubt that she was going to be a melismatic force to be reckoned with for years to come.

“We don’t acknowledge numbers, but we do acknowledge when it’s time for a celebratory moment!” the 50-year-old Carey — who typically refers to her birthdays as “anniversaries” — tweeted on Friday.

And what a moment it was when Carey, accompanied only by piano and three background singers, announced her arrival before she was even old enough to drink at Club Tatou.

The archival footage also arrives with a digital EP, “The Live Debut — 1990,” which captures Carey’s performance at the intimate venue. Also included are her breakout single “Vision of Love,” another No. 1 ballad, “Love Takes Time,” and “Vanishing,” one of her best early deep cuts.

There’s also a gospel-fied rendition of Ben E. King’s “Don’t Play That Song (You Lied),” which Aretha Franklin covered on her 1970 album “Spirit in the Dark.”

“I need an extra song, so I added ‘Don’t Play That Song for Me,’ by Aretha Franklin, and it’s like I do it in concert . . . I say to the people, ‘This was originally recorded by the incomparable Aretha Franklin,’ and I just say it so they know I don’t think I’m even coming close to the way Aretha sang it, but this is my tribute,” Carey said in an archival interview.

The five-time Grammy winner also added, in true diva fashion, a disclaimer on Twitter: “The olive green crushed velvet ensemble was not my choice!”

Stay tuned for more MC dish when she releases her memoir, “The Meaning of Mariah Carey,” on Sept. 29.
