Robert Plant got the rumor mill churning earlier this year when he mentioned that he had “nothing to do in 2014.” Unfortunately, Plant is not the only member of Led Zeppelin, and it looks like John Paul Jones will be too busy for a reunion tour next year.

In a recent interview with The Guardian, Jones said that he will spend 2014 adapting a 105-year-old Swedish play into an opera. The bassist explained that he has written half of the first act for the production—an adaptation of August Strindberg’s Spöksonaten.

The surviving members of Led Zeppelin came together on a few occasions last year to promote their concert film Celebration Day, and to accept honors from the Kennedy Center in Washington, DC.
