Jasmine Trias, the "American Idol" finalist from Hawai'i, is guesting this summer with the Society of Seven Las Vegas in a nightclub endeavor that will earn her an orchid for her hair — an upgrade of the plumeria that became her trademark on the reality show's third season.

Trias, who previously showcased her tremendous growth and expanded repertoire in making the leap from TV and concerts to mainstream showroom (she is the first of the "Idol" alums to work Vegas, with the original Society of Seven combo at the Flamingo hotel), is stretching and strutting like a real trouper at the Main Showroom of the Outrigger Waikiki on the Beach. She opened last Friday night.

Interestingly, two tunes — "Rhythm Is Gonna Get You," which opens the show, and "This Is the Moment," which brings down the curtain — sum up her first Waikiki gig: She is moving and grooving and cultivating a niche that will serve as a bridge to more concert and club work, here and abroad. This, indeed, is her shining moment in her hometown.

Amid the vigor of the SOS crew, Trias brings girl power and glamour to center stage. She makes it the Society of Eight, carrying her weight as she recapitulates her "Idol" years with "Mr. Melody" and "Inseparable," tunes that made her the darling of the tube four years ago. "How can I forget," she says, adding a plumeria blossom over her right ear.

As an SOS ally, she embraces impersonations with confidence and charm, adding comedy to her Britney Spears and engaging in exotic dance as Shakira. She even does Beyoncé — with wig and costume adornments — with a bit of choreographic moves with the guys.

She is integrated into the usual SOS mix, best displayed in a new montage of Broadway excerpts that features her doing three tunes, "Happy Talk" from "South Pacific," "I'd Give My Life for You" from "Miss Saigon," and "And I'm Telling You I'm Not Going" from "Dreamgirls" that demonstrate savvy song selection with wide audience appeal.

That segment is part of a rebundled Broadway medley that features tunes and costumes from previous SOS spectacles, including John Salvatera doing "That's All I Ask of You" from "Phantom of the Opera," a reunion on "Beauty and the Beast," a splendid "All That Jazz" sequence with gunmen and Jonathan Kaina tap dancing to "All That Jazz," capped by the show-closing "This Is the Moment" from "Jekyll and Hyde."

There are fingerprints of SOS founder Tony Ruivivar in all of these proceedings; he is the godfather of both this and the Las Vegas-based classic SOS.

The other SOS LV guys have their moments, too: Glenn Miyashiro dolled up as Cher to Salvatera's Sonny; Salvatera as Nat "King" Cole to Trias' Natalie Cole; Freddy Von Paraz as the satisfying Jumping Jack Flasher Mick Jagger; Salvatera as Sammy Davis Jr., Miyashiro as Dean Martin and Richard Natto as Frank Sinatra and the Rat Packers; Mike de Guzman as Joe Cocker; and William Daquioag in a myriad of supporting roles.

Yep, nostalgia looms large, with big-band swing, The Beatles, the Village People and Elvis Presley. And Bruddah Iz's "Over the Rainbow" serves as the introductory Yellow Brick Road to a host of impersonations.

The Beatles thing is mounted with a Sgt. Pepper's Lonely Hearts Club Band motif and walk-through-the-audience musicianship, leading to a splendid recapitulation of faves — with a little bit of help from the Lennon-McCartney catalogue of blockbusters. You're expected to sing along, too, on some tunes.

With this engagement, Trias is building her foundation as an entertainer, one of the goals of her visit. If you want to catch up on her progress, and be reintroduced to the musical and comedic hijinks of the SOS LV, this is the prime time to book a table.
