Sinead O'Connor is to feature on two tracks on the new Massive Attack album.
The band have chosen 12 new tracks for the as-yet-untitled album.
They had around 850 recordings to choose from.
Massive Attack are remixing the album in June and July, and plan to release it in the autumn.
A posting on the official Massive Attack website says: "Everyone knows how great Sinead is as a singer but she's very versatile as well.
"She's done two very beautiful songs. One is very political, one more personal."
