A pure entertainer like Ms. Minnelli - and there is none purer - is at once voracious and extravagantly generous.  From the moment Minnelli joins forces with a male singing and dancing quartet to resurrect parts of a famous nightclub act Kay Thompson created in the late 1940s and early '50s with the Williams Brothers, the Palace Theater blasts off into orbit.  Ms. Minnelli and the quartet execute production numbers that are the last word in modern pop-jazz virtuosity from an era when the term modern meant sleek, cool, jet-propelled sophistication.  Clad in identical black suits, white shirts and skinny ties, delivering impeccable, jazz-inflected barbershop harmonies as they swoop and glide, Johnny Rodgers, Cortes Alexander, Jim Caruso and Tiger Martina perform astounding feats of singing and dancing coordination. They are assisted on the piano by Billy Stritch, who breaks in to provide creamy vocal fills.  The director Ron Lewis's choreography belongs to the vintage variety-show sort, but is stripped of clichés to the point that it transmits joy and enthusiasm to the audience like an electric charge.

Liza is given glorious support by Cortes Alexander, Jim Caruso, Tiger Martina and Johnny Rogers as the new Williams Brothers.  These guys are out of this world, so sexy, assured, amusing, all equipped with rich melding voices, and dance skills to die for.  Liza's old friend, pianist, arranger Billy Stritch also jumps in on one of the numbers.  He is great too! The emotion, the history, the tenacity, the glamour and vibrancy of Liza Minnelli-just when you think she has finally depleted, like a great oil well sputtering down, out comes another gusher.  Liza Minnelli--they broke, stepped on and ground up the mold when they made her.  Right now she is standing in the brightest light, at her best, giving and receiving the love she values most.  Please don't miss Liza in her four weeks at the Palace.  It is magic. It is theater.  It is show biz beyond the pale.  It doesn't get any better.

This show is perhaps the ultimate tribute to ultimate tributes, impossibly irreplaceable…the numbers are excitingly exhausting to watch, but Minnelli doesn't just survive them, she triumphs over them…she's no mere force of nature, she's a force of the universe.  Given what she does in “Liza's at the Palace,” one cannot imagine 2008 going out with a bigger or more heavenly bang.

Liza With An A+!  This show is the sort of late-career triumph of which show-business mythology is made.  Liza blends her life and her art in the way that only a true legend can.
New York Post

Santa came early this year - with a fabulous present wrapped in shiny sequins and shimmering stardust: Liza Minnelli.  Her spectacular holiday happening "Liza's at the Palace ..." finds Liza with a Z fit, funny, surprisingly energetic and in her best voice in ages.  The Williams Brothers are played here by the fantastic Cortés Alexander, Jim Caruso, Tiger Martina and Johnny Rodgers.  Minnelli and the fab foursome bring back to life Thompson's act and recreate the delightful sounds and harmonies of the nightclub era.  During "Jubilee Time," "Clap Yo' Hands" and "I Love a Violin," the company ignites the stage with joy and enthusiasm.  Liza Minnelli is one of a kind.
New York Daily News

Rockefeller Center may have lit their Christmas tree last night but when Liza Minnelli stepped on stage of the Palace Theatre and struck her classic pose in her dazzling white outfit and t-strapped sequined shoes, looking fit and fabulous she gave off a thousand times more radiance than that old tree could ever muster.  A standing ovation greeted her before she sang a single note.  Liza is an absolutely exciting, electrifying, exhilarating phenomenon.  “Liza's at The Palace” is a brilliant blend of concept, execution and star quality.  She is a force of nature with guts and confidence and a power house personality who can still send chills up and down your spine with her incredible renditions of “Cabaret” and “New York, New York”.  But the piece de resistance is the recreation of Kay Thompson's nightclub act of 1948 at Ciro's where Liza as Kay is backed up by the Williams Brothers - here portrayed by the best four back up men in suits and ties in the business - ever - Johnny Rodgers, Cortes Alexander, Jim Caruso and Tiger Martina.  They are fabulous.  The act is fabulous.  You have got to see it to believe it.  Now that's entertainment!

Time-traveling to Ciro's in 1948, Minnelli and the boys present a zesty facsimile of Thompson's legendary act, with its sophisticated arrangements, jazzy harmonies and snappy choreography.  And when Minnelli exits while the guys sing the Gershwins' and Gus Kahn's “Liza (All the Clouds'll Roll Away),” the interlude is far more buoyant than any mere filler number.  Particularly in this section, which relies on elements beyond Minnelli herself, the polish of director-choreographer Ron Lewis' work is evident.  The four Williams Brothers sing and dance and take us back to the 1940's with their amazing dance and old fashioned crooning singing styles.  These guys sure can dance and have a wonderful chemistry with Liza.  One that appears quite deep indeed, like a long-lasting friendship.
Applause

Liza Minnelli has sunny star-wattage to spare, a never-say-die attitude that is astonishing to watch.  The evening is called "Liza's at the Palace," and it would be foolish if you don't catch her act before it closes Dec. 28.  Minnelli doesn't stint in her show.  She's onstage for a full two hours, exiting only in the second act for a brief time to allow for a terrific four-man chorus - Johnny Rodgers, Cortes Alexander, Jim Caruso and Tiger Martina.  With an assist from them, Minnelli recreates a bit of Kay Thompson's late 1940s nightclub act.  A witty, sophisticated woman, Thompson had a style and flair all her own that Minnelli effectively channels in this amazing show.  Somewhere, Thompson must be smiling.

By the time Liza is taking in her ninth or tenth standing ovation of the first act, the reactions of a crowd going nuts for her nourishes her performance of "Cabaret" to the point where the newly found strength of her voice and the age-defying grace of her movements burst into a mesmerizing force that would be considered the high point of any show that didn't end its second act with a "New York, New York" so powerful and emotionally vibrant you'll be checking the theatre's water fountains for the one marked "youth."  The evening is saturated with class from start to finish.  Joined by the sensational song and dance quartet of Johnny Rodgers, Cortes Alexander, Tiger Martina and Manhattan cabaret gem Jim Caruso, they recreate the excitement of a live Thompson performance with "Hello, Hello," "Jubilee Time," "Basin Street Blues" and a breakneck speed "Clap Yo' Hands," all snappily staged with Lewis's period supper clubby choreography.

Minnelli is probably the last shining star of her kind.  There are no more supernova triple threats who glitter equally brightly on Broadway, in films, and on television.  Grab this chance to bask in her radiant talent at full blast.  To coin a phrase, they don't make 'em like that anymore.
Backstage

Liza With A Zowie!  Minnelli erases any question about her raw power to continue to command a stage and enrapture an audience.  Four terrific song-and-dance men accompany her in the second part.  They all add fuel to her fire, but Minnelli clearly is the flamethrower, with a knock-'em-dead voice whose come-hither beckon is still as rich as its belt.
Philly News

The opening night audience of Liza's at the Palace experienced the stuff of a survivor, a legend. The concert…will end up being written about - for years.  Minnelli not only razzle-dazzled but also rang them bells.  Her performance could be described as nothing less than a miracle.
BroadwayStars

LIZA-with-a-Z for Zip, Zest, Zowie.  Maybe she lacked love from the chorus line of husbands, but her fans sure bathed her in it.  Opening night of a jammed "Palace" - I saw Tony Danza, Shirley MacLaine, Rex Reed, Tommy Tune - on their feet screaming for her.  Robert De Niro had come for dress rehearsal.  And when she did "New York, New York," you could've heard the stamping and hollering in New Mexico.  Good to have Liza back.
