The Evolution of Adam Lambert

After kicking off the set with the album’s title track, the 30-year-old American Idol alum told the packed crowd of radio winners, "I’m so happy I finally got [the album] out to you guys!" (Trespassing had originally been scheduled for a March 20 release.)

The 200-strong crowd of so-called Glamberts answered back with chants of "Number one! Number one!" -- which is exactly where Trespassing ended up on iTunes less than 24 hours after going on sale.

Clad in a silk, leopard-print shirt under a black suit, Lambert performed a funky, often upbeat set of nine songs -- eight from the new record. Stand-outs included a stripped-down version of his 2009 hit, the Pink-penned "Whataya Want From Me" (only a piano and occasional kick drum accompanied his impassioned vocals), and Trespassing's "Naked Love," which the singer said is "about people just being honest with each other in relationships."

Forty minutes later, the rocker finished up -- sans suit jacket, to the delight of the mostly female crowd -- with his new single, "Never Close Our Eyes."

Fans stood in line all day long on the mostly rainy New York day to be close to their idol, whose show was broadcast live on KTU.com and iHeartRadio.

Lambert performs this Thursday night on American Idol before heading back east to do a set at NYC radio station 103.5 KTU’s summer concert, KTU-phoria, alongside Pitbull, Flo Rida, Enrique Iglesias and others.
