Sinead2 More than 30 years after Jackson Browne, Bruce Springsteen and Bonnie Raitt gathered for the No Nukes concert at Madison Square Garden, a new group of celeb activists is sounding the clarion call warning about the dangers of unfettered atoms.

Composer Jonathan Elias has enlisted Sting, Sinead O’Conner and Robert Downey Jr., among others, for “Prayer Cycle 2: Path To Zero,” the proceeds from which will go to Global Zero (http://www.globalzero.org/), an international organization dedicated to nuclear disarmament.

The album will be released May 10 on Across the Universe Records. Featuring more than a dozen different artists singing in multiple languages and genres, “Prayer Cycle 2” also features Serj Tankian, Alex Ebert, Jonathan Davis of Korn, Afro-pop singers Salif Keita and Angelique Kidjo, Jon Anderson of Yes, Lilli Elias and Pakistan’s Rahat Fateh Ali Khan.

There’s even a cameo from the late Jim Morrison, reciting poetry from an unreleased recording.
