Gems: The Duets Collection may bear a title that suggests it’s a compilation, but this 2011 effort is a brand-new album containing nothing but new collaborations between Michael Bolton and similarly minded travelers of the middle of the road…

By the evidence of My Secret Passion, Michael Bolton's secret passion is opera. For several years, he had included arias in his concerts, but he had never recorded them until My Secret Passion. Bolton's bombastic style is relatively well-suited to arias, since he certainly can project his voice quite powerfully. He doesn't have the subtlety to deliver this repertoire completely convincingly, but the Philharmonia Orchestra, under the direction of Steven Mercurio, helps camouflage his weaknesses, as does the guest appearance of soprano Renee Fleming. In other words, My Secret Passion isn't the disaster that Bolton's detractors were expecting, but it isn't a triumph, either. Instead, it's a welcome change of pace from a singer who has become a touch too predictable.

The U.K. collection The Very Best of Michael Bolton – initially released in 2005, repackaged as a slide pack in 2007 – is a good overview of the singer's peak years, containing all the big hits except "Love Is a Wonderful Thing" (only natural, considering the lawsuit surrounding the song) in a 17-track compilation that should give most listeners all the Bolton they need.

So this is where we find our hero in 2003. Dropped from his major label and absent his trademark flowing golden locks, Vintage presents his fans with yet another set of standout ballads and standards done only the way the Bolton can. Kicking out the jams early on with "The Very Thought of You," the tone is set right away for the album as a perfect musical accompaniment to a romantic dinner. The smooth, sultry tone is brought to a rousing climax with his re-interpretation of Etta James' classic "At Last." The fun continues onward with "Daddy's Little Girl," which was featured prominently in an ad campaign. Vintage closes with the potent but loaded question of "What Are You Doing the Rest of Your Life?," a stunning finish to an album sure to appease even the most loyal of his fans.

Singer/songwriter Michael Bolton emerged in the mid-'80s as a major soft rock balladeer. Originally, he recorded under his real name, Michael Bolotin, turning up on RCA Records in the mid-'70s singing cover tunes and his own blue-eyed soul songs in a voice reminiscent of Joe Cocker. He then became the lead singer of Blackjack, a heavy metal band that made two albums for Polydor before splitting up in the early '80s. Looking to relaunch his career, he changed his name to Michael Bolton and signed to Columbia Records as a solo artist in 1983. Bolton's achievements include selling more than 75 million records, recording eight top 10 albums and two number-one singles on the Billboard charts, as well as winning multiple American Music Awards and Grammy Awards.
