Vanessa Carlton will release Harmonium, the follow-up to her 2002 Grammy-nominated debut Be Not Nobody, on October 19th. The album's first single "White Houses," featuring Fleetwood Mac's Lindsey Buckingham on acoustic guitar, will hit radio in August.

Carlton recorded the album in San Francisco with boyfriend and Third Eye Blind frontman Stephen Jenkins co-producing, and it promises to be much darker than its predecessor.

"I'm singing about suicide, insomnia and paranoia," Carlton told Rolling Stone last year, during the sessions. "There's nothing piano recital-y about it. It's goth."

"I think I'm more evolved, more secure in who I am," she continued. "I'm beyond the diary-confessional chapter of my writing."
