Kicking off another typical seven-day work week in the offices of his management company, 19 Entertainment, Adam Lambert fixed his gaze on his own pretty face. Scattered across his publicist's desk were proof sheets from a photo session with the singer, who released his debut album on RCA Records, For Your Entertainment, recently. The shots captured Lambert in typical glam-god poses: peacock, street tough, space oddity, freaky adventurer in the boudoir of the damned.

Lambert, who in person is none of those things but rather a startlingly grounded 27-year-old radiating Southern Californian optimism, took up a red pencil and circled a frame. "This one needs a little fix here," he said, momentarily playing art director. It's all part of one big performance for Lambert as he works to resurrect rock in the new pop age.

But hold on. When such hyperbole is thrust at him — by, say, an overly admiring pop critic who followed him closely during last year's American Idol contest, when he broke ground as the most successful Idol to be rock-oriented, androgynous and gay — he lifts a ring-laden hand to brush it away.

"I want to put it out there that I don't take myself all that seriously," he said. That's one of his mantras. "The dress-up supports that; the fantasy element supports it. People want to talk about whether I have rock cred, whether I'm selling out, the theatricality, the gay stuff. ... Chill out! And just enjoy yourself. It's not that deep."

Then he corrected himself, slightly. "Sometimes it is deep. Some of the songs on the album are," he admitted, pointing to the song Soaked, a sweeping epic about the loneliness of one-night stands that's actually a cover of an unreleased track from Muse, and a very serious one at that. He also singled out Broken Open, a ballad he co-wrote, which he said is about encouraging a lover to become vulnerable enough to cry.

"But sometimes it's just, ‘This is hot, I feel good, this song makes me want to go get a drink and flirt with somebody and have a good time.' Good energy is just as credible as the cathartic, dark, heavy [stuff]," he said. "It's just as important!"

This might be the most exciting message Lambert carries forward into one of the most intensely observed major label debuts in recent pop history. He's reminding America that rock music can be joyful, light-spirited and sublimely silly, just as pop can explore serious subjects beyond the call to hit the dance floor. And that a rock star might also like to dance.

Peaceful outrageousness

As Lambert plays the role, a rock star doesn't have to be an angry punk, a brooding post-grunge puritan or a hair-metal style macho dude in a dress. These approaches all have their purpose, but Lambert projects something different: outrageousness that's totally at peace with itself.

He does this by connecting counter-cultural ideas — values he learned as a kid touring Germany in a production of Hair, the musical that first brought rock's spirit to Broadway — with a trouper's sense of artistic performance as work, which takes brains and a certain sharpness as well as talent.

"His No 1 challenge, which I think he'll pass, is stay true to himself and to roll with the punches as they come," said Rob Cavallo, who has worked with a range of artists including Green Day and the Dave Matthews Band and produced four tracks on For Your Entertainment. "He's going to have successes. He might have people against him. Which is exactly what happened to Elvis, the Beatles, to Prince. ... There will be controversy, and there will be opinions. If he stays true to himself, he will be one of those great artists to watch over the years."

Lambert readily admits a huge debt to David Bowie, whom he describes as "my favourite", and other glam and classic rockers such as Mick Jagger and Marc Bolan of T. Rex. Lambert's efforts to succeed as a rocker will hinge on his ability to tap into the legacy Bowie and those others represent. His "emo" side, linking him to bands like Fall Out Boy, also helps. But it's hard to know if the rock world — and rock radio, in particular — will embrace him.

Success in both

"When bands like Fall Out Boy and All American Rejects first came out, they got airplay on modern-rock stations," noted Leslie Fram, a rock radio veteran who's programme director of New York's 101.9 RXP FM and co-host of its morning show with Matt Pinfield. "But when they crossed over to the Top 40, it was the nail in the coffin. They went over to the pop side, image-wise, and modern-rock radio wanted nothing to do with them."

Lambert's trying something even these bands didn't attempt — to succeed in both the rock and pop camps at once. He loves his glam, but he admits that in terms of today's stars, he has more in common with Beyoncé than with Chris Daughtry.

"People look at me and immediately say, ‘Oh, he's doing the musical-theatre thing,'" he said. "But if you look at most female pop stars right now, how are they any less theatre? Beyoncé is doing Single Ladies with two girls in character shoes and leotards, doing Fosse choreography from Sweet Charity, and West Side Story."

Lambert is certainly enjoying his bigger budget now — especially the "expensive, beautiful and weird" clothes — but he seems to have preserved the perspective he gained hanging out with serious bohemians.

He does know how to play the music industry game. He raided the executive suites for collaborators on For Your Entertainment: its songwriters include ubiquitous hitmakers Max Martin, Ryan Tedder, Linda Perry, Dr Luke and Idol judge Kara DioGuardi, and his producers include big names like RedOne and Cavallo. "Adam is unusually confident in my mind but not in a pretentious way," Tedder said in an e-mail. "He has the confidence of a guy that absolutely knows who he is to the core, both musically and personally. He spent four days in Denver working with me and was as laid back and comfortable in my studio as he was being swarmed by fans when we went to dinner. For a first-time artist, he definitely had more control creatively than I've ever seen a new act given, but Adam is the kind of person that would rather not put out anything than put out something that was less than 100 per cent his vision."

Pinfield, Fram's co-host on RXP FM and a defining force within alternative rock as an MTV host during the 1990s, thinks his eclectic approach could work for Lambert. He might have a tough time on rock radio, Pinfield said, but the singer's fans might not care.

"There was a different world before, with the rock 'n' roll thing," he said. "Today, the same kids who love the Beatles and the Stones and Zeppelin could love Radiohead and Adam Lambert. Young people today are not as worried about being genre specific."

In the studio, Lambert enlisted hot ingenues Pink and Lady Gaga as writers while securing some of that fabled rock cred by covering material by Justin Hawkins, formerly of English glam revivalists the Darkness, and Muse, a band he loves.

‘Masculine persona'

"I listen to crazy, robust rock music where they sing their faces off, and soul music, which can be similar," Lambert said. "But I also listen to a lot of dance music. I love that style. I was a Paula Abdul fan, a Michael Jackson fan, a Madonna fan. When Christina Aguilera came out when I was in high school, that was a great example of someone taking the pop-dance feel but who could really sing. Pop stars have done it; it's just not a lot of guys have done it. Maybe it's a question of masculine persona."

His playful pan-sexuality and flamboyant swagger, once qualities common to hard rockers, are now owned by the likes of Pink and Lady Gaga. Lambert understands that. He also cites Justin Timberlake as a kindred spirit, if not musically, then in terms of showmanship and fluid style.

"I think the next generation coming up is a little bit more open-minded," he said. "More accepting, more colourful, more multi-genre, multiethnic, multi-sexuality, which is more utopian. Or I think so. I hope so."

What separates Lambert from much of pop's young elite is his voice, an instrument whose timbre, power and range recalls those titans of hard rock.

"He can sing almost any note on a guitar from the lowest to highest," said Cavallo, who thinks Lambert's sense of style and soul, combined with that range, puts him in the realm of the greats. "And if you're in the studio with him and say, ‘Can we get a little more dirty?' he'll go ‘Waaaaah!' And then the microphone is melted and the speakers have exploded."
