Rock ‘n’ roll great Grace Slick has gone all “We Are The World” on the Deepwater Horizon, joining with songwriter Michelle Mangione on a new song called “The Edge of Madness.”

Slick’s song will be used to raise money to help Louisiana recover from the spill. The Grammy Museum partnered with the artists on the song, which had its debut July 24 at the museum.

The recording features more 20 artists, including Bill Medley (Righteous Brothers), Tom Dumont (No Doubt), Billy Zoom (X), Martha Davis (The Motels), Kid Ramos (The Fabulous Thunderbirds), Larry Hanson (Alabama), Terri Nunn (Berlin), and Steven Hodges (Tom Waits, Smashing Pumpkins).

“Grace was so pissed off by Louisiana being hit from every angle, between Katrina and now BP, that she sent me these lyrics and asked me to write the music,” Mangione said. “We started putting out the word to other musicians and singers who also felt helpless and wondered what they could do. Then the parts just started coming in.
