Rocker Beck has blamed a "severe" spinal injury for forcing him to scale back his music output in recent years.
The Loser hitmaker, 43, went public his health issues in an interview with Argentina's Pagina/12 newspaper, admitting the ailment has hindered work on the follow-up to 2008's Modern Guilt.
In the article, which has been translated into English on TheFutureHeart.com, he says, "I had some injuries. I had severe damage to my spine, but now it's improving so I'm back in the music. It was a long, long recovery. Lately I concentrated on playing guitar. Do not think I can move again as before, although I can give a lot onstage."
Beck, who is due to release his 12th studio album, Morning Phase, next year (14), also reveals he had an album of new material in late 2008, but the tracks "stopped ringing fresh" for him and he abandoned the work until 2010, when he resumed the project.
The musician has not been completely out of the public eye during his health struggle - he contributed to albums by Charlotte Gainsbourg, Thurston Moore and a collection of Philip Glass remixes, and he also reworked David Bowie's Sound + Vision earlier this year (13).
Morning Phase, which is set to be unveiled in February (14), is described as a "companion piece" to Beck's 2002 album Sea Change, which focused on acoustic tracks.
