Update (4/21): It's time to get your whistle on. Adam Lambert's new single "Ghost Town" is here in full. 

Like we heard in the initial teaser, there's an incredible, pumping house beat backing an ominous whistle hook—but that's the chorus. To get up there, we have a tame, acoustic guitar build up that sees Lambert crooning melancholy-yet-slightly-theatrical lyrics like "Died last night in my dreams / Walking the streets of some old ghost town / I tried to believe / In God and James Dean, but Hollywood sold out." It's a touch of the drama we love from Adam, but brought to a new, mature light. That evolution is also felt in the vocal approach, that still gives showcases of the singer's pipes, but he doesn't need to wail the entire time and goes for a more subtle approach.

There's a bit of disjointedness from the acoustic strums to the heavy beats, but once the second chorus hits we're submerged in this swirling, dark-house production that sounds so fresh, but accessible enough for Top 40 radio. 

"Ghost Town" is the first single from Adam's upcoming album The Original High. Check out everything we know about the record right here.

Original Story (3/23): From American Idol to house icon? Adam Lambert announced his new single "Ghost Town" with a small video clip on Instagram that not only showed some sexy shots of the singer, but also previewed the upcoming track. (Scope it out below.)

It's only 15 seconds, but "Ghost Town" appears to tout a throbbing house beat accompanied by an ominous whistle hook. We don't get to hear any vocals from Adam, but we're already getting goosebumps imagining him belting over that beat. If anyone thought whistles were getting stale in pop music (from Maroon 5's "Moves Like Jagger" to OneRepublic's "Good Life" to Flo Rida's terrible innuendo-driven "Whistle" to the brand new "All Day," Kanye West's monster track built around a Paul McCartney whistling bit), Lambert just totally refreshed the trend.

"I think people are going to be really surprised," Adam told Billboard of his upcoming single. He further explained his new sound, adding:

"I wanted something more internal and more grounded. A little less with the theatrical and the camp and the presentation. I wanted to bring it in a bit more. Being on the road with a British rock band, and being in London a lot this year, rehearsing with them and doing TV gigs, I think that has affected my sound and where we are headed with it. [Europe] is very ahead of the curve, or right on, and I was definitely influenced by that. Vocally, it's very intimate compared to what I've done in the past. There is a little bit of a daring, deeper internal conflict and poetry about it...the album feels like a new era for me—emotionally, lyrically, sonically. It feels fresh, it feels new. It's still me. It's still stuff that fans know and love but it's a new chapter 100 percent."

"Ghost Town" is the first taste of Lambert's forthcoming album, The Original HighAs previously reported, his third full-length will be executive produced by "Whataya Want From Me" boardsmiths Max Martin and Shellback and released on Warner Bros. Records following creative differences with former label RCA.

The Original High is due out this summer, while "Ghost Town" drops April 21. Glamberts, are you ready to dance?
