Adam Lambert To Release Acoustic Album

Singer says unplugged set will be out before end of the year.

Justin Bieber isn't the only newbie star preparing to release an acoustic set. Former "American Idol" runner-up Adam Lambert revealed in a recent interview that he's prepping an unplugged disc for the holidays as well.

Lambert, speaking to Australian talker Dylan Lewis, said he would like to have the album out around Thanksgiving or in early December. "There is going to be an acoustic CD," said Lambert, who didn't reveal the title or track listing. "I don't have an exact release date. Probably around Thanksgiving time — November, December." If he does hit that date, he could face off against Bieber's acoustic set, which is slated for a November 23 release.

"We went around Europe in the earlier part of this year ... and we did a lot of promo, so I had Monty, my guitar player, and my drummer at the time ... We just did very stripped-back versions of the songs. We got our hands on some of those recordings. Then we also recorded some of the stuff from the actual Glam Nation Tour, so it's going to be a mix of both," he said of the on-the-road sessions that produced the acoustic and live songs tracked during the worldwide tour in support of his nearly 750,000-selling 2009 debut, For Your Entertainment.

Lambert was also asked when he might start working on his second proper album. "There's a new album that is definitely being theorized," he said. "It's being thought about, it's bubbling to the surface. I have things that I'm writing down, little notes that I'm writing here and there, but nothing's started yet on it. But hopefully it'll be out by the spring or summer of next year."

Having snagged Lady Gaga, Muse's Matt Bellamy and Pink for his debut, Lambert, of course, has a deep wish list of artists he'd like to collaborate with on the new disc. Foremost in his mind, though, is Christina Aguilera, whom he said he's reached out to a few times already to no avail. "Her voice is power," he said.
