Michael Bolton adds an interesting slant to “The Music of Andrew Lloyd Webber” now showing at the Palace Theatre. Famous for his throaty romantic songs, Bolton modulates his singing style to a degree in an effort to blend into the musical theater genre with surprisingly good results.In the past, Bolton has shown chameleon-like musical tendencies by appearing with Luciano Pavarotti and holding a number one spot on the classical music charts with an aria album. His performance in “The Music of Andrew Lloyd Webber” is yet another successful crossover for Bolton, especially his performance with Maria Couch of “Phantom Duet” from “The Phantom of the Opera,” a musical about a man whose heart is tortured by the shunning of society due to his horribly disfigured face.Bolton can comfortably add his performance in theater to his victory list containing six Grammies for Best Male Vocalist, six American Music Awards, worldwide concert sellouts, sales of more than 52 million albums and singles, as well as songwriting for other entertainers, including Barbara Streisand, Bob Dylan, Kenny Rogers and Joe Cocker.Perhaps the only disenchanting aspect of Bolton’s performance is his wardrobe. In his first appearance in the show, Bolton was dressed in black leather pants and a black casual long-sleeved shirt with the cuffs unbuttoned. In the second, he wore a blue suit, which, although pressed, somehow gave him a rumpled appearance. These outfits were in stark contrast to the other cast members’ elegant attire. Though Bolton is given starring credentials in this show and is allowed to stand out, he would do well to remember that this is theater and he should dress accordingly.The best and liveliest aspects however, came not from Bolton, but from the supporting cast. This group is a showcase of talent and should not be missed. In order of appearance: Sal Sabella, Kevin Reed-Cohen, Michael B. Minarik, Rebecca Simon, Laura Bonello, Gaelen Gilliland, Amy Persons, Michael Gillis, Craig Laurie, Maria Couch, Aimee Neale, Matt Witten, Fabiola Reis and Nick Sattinger. Quite obviously trained for the musical theater stage, their voices resonate not only acoustically, but also with the passion of the characters for whom the songs were originally written. A beautiful and haunting performance is given by Fabiola Reis who sang “Think of Me,” from “Phantom of the Opera,” as she reaches high notes with such depth and projection that it literally gives the audience an adrenaline rush. This was cause for ovation almost equal to that given to Bolton. It is a shame that more credit is not lavished on these talented entertainers in publicity or in the show’s program.For those who have gone to musicals in the past, this show should be viewed with an open mind. There are few costume changes during the performance and very little dancing. These performances are a collaboration of music from Andrew Lloyd Webber’s works and no background information is provided for each song which detracts slightly from the flavor and circumstances for which they were written. The supporting cast does most of the singing and are dressed in black evening dress wear, the only exception being Gaelen Gilliland, who wore a white ballroom gown and performed “Don’t Cry For Me Argentina” from “Evita.””The Music of Andrew Lloyd Webber” will be at the Palace Theatre until June 25. Evening shows are 8 p.m., with matinees at 2 p.m. on Saturday and Sunday. Tickets range from $19 to $59 and are available at the Palace Theatre Box Office, TicketMaster or charge by phone: (614) 431-3600.
