Rockers the Manic Street Preachers are releasing the last song they wrote with missing guitarist Richey Edwards.
The 27-year-old has not been seen for eight years and his disappearance remains a mystery.
Band members James Dean Bradfield, Nicky Wire and Sean Moore carried on without him, and on July 14 will release an album including a track called Judge Y'rself, the last written before Richey went missing.
It was recorded for the soundtrack to Sylvester Stallone film Judge Dredd but never released.
Money from sales of the album, called Lipstick Traces - A Secret History of the Manic Street Preachers - will boost the trust fund set up in Richey's name by the other band members.
A band spokesman said: "It's very emotional for them to put out this track because it's the last they wrote as a four-piece."
The double album includes unreleased tracks and B-sides. It also includes cover versions of some of the Manics' favourite songs.
