Songs of Mass Destruction, Lennox’s first new release since 2003’s Bare, is due out October 1 in the U.K. and October 2 in the U.S. The disc was recorded in Los Angeles with producer Glen Ballard, marking the first time the singer has made a solo project without long-time producer Steve Lipson.

The album features 11 signature Lennox songs, including “Ghosts In My Machine,” “Through A Glass Darkly,” “Fingernail Moon” and “Dark Road,” the first single.

Another track, the feminist anthem “Sing,” will be released as a benefit single and features guest vocals by 23 female solo artists, including Madonna, Celine Dion, k.d. lang, Sarah McLachlan, Melissa Etheridge, Joss Stone and Bonnie Raitt.

The song also includes a contribution by The Generics, a vocal group made up of members of the Treatment Action Campaign, an organization fighting for human rights, education and health care for those affected by the HIV/AIDS virus.
