Manic Street Preachers have revealed they are working on a new album solely inspired by lyrics from missing member Richey Edwards.
The band are currently holed up in a studio with producer Steve Albini on their ninth album.
A statement on the band's website said: "All the songs we are recording are lyrics left to us by Richey.
"Finally it feels like the right time to use them (especially after the last 18 months with Send Away The Tigers)."
It added: "We have been in the studio recording live - to tape - analogue - no digital hiss - no Pro Tools - no safety nets. Quite scary, daunting but invigorating.
"Musically, in many ways it feels like a follow up to The Holy Bible but there is also an acoustic side - tender, romantic, nihilism, Small Black Flowers That Grow In The Sky-esque.
It's a record that celebrates the genius of his words, full of love, anger, intelligence and respect. We have to make this great. Wish us luck."
Former guitarist Richey Edwards disappeared from the Embassy Hotel at Bayswater Road in London on 1 February 1995.
His car was found abandoned on 17 February, 1995 at a service station near the Severn Bridge. His disappearance still remains a mystery.
The Welsh trio said they are hoping to release the follow-up to Send Away The Tigers next April or May.
The band are currently juggling working album titles Journal for Plague Lovers and I Know I Believe In Nothing But It Is My Nothing.
