For rock fans, Adam Lambert [ tickets ] was the most exciting contestant in the history of "American Idol." In a sea of wannabe Mariah Careys, Whitney Houstons, and bland Daughtry-lite rockers, Lambert had a voice, flair, and style that recalled rock greats from Queen's Freddie Mercury to Guns N' Roses' Axl Rose.

Yet, those hoping Lambert would carry the rock torch into the studio on "For Your Entertainment" will be sadly disappointed. More often than not, the artist known as "Glambert" has his glittered-up eyes on the dance floor or introspective ballads rather than the arena-rock stage.

As is the case with almost all the "Idol" alums, Lambert is more of a performer than a songwriter. While the Glam-one does have co-writing credits on four of the album's 14 tracks, he's called in favors from a gang of well-known writers and producers, which results in a game of "spot the collaborator."

Album-opener "Music Again," penned by Justin Hawkins of the ill-fated glam-metalists The Darkness, is an '80s-sounding pop-rocker with some crunchy power-chords and Queen-flavored vocals, but never really takes off. The title track, co-written and produced by pop Svengali Dr. Luke, sounds like a Britney Spears dance-floor basher, with one major difference: Lambert can actually sing. The anthemic "Whataya Want From Me" rocks like a feisty Pink track, and not surprisingly, she co-wrote it.

Elsewhere, we get Lambert channeling Queen's Mercury in "Soaked," the piano-driven ballad penned by Muse's Matthew Bellamy, trying on a little Weezer-flavored pop-rock in the Rivers Cuomo co-write "Pick U Up," and getting sassy like vintage George Michael in the gyrating "Fever," Lady Gaga's contribution.

While all of the above certainly have hit potential, they don't really provide any insight into Lambert's life and personality. It's almost as if he's just trying out different collaborators like stage outfits, hoping that the audience will be wowed by the costume changes. Thus, there's a lot of musical flash on "For Your Entertainment," but ultimately it leaves you feeling a bit empty and wondering exactly who Adam Lambert really is.
