Led Zeppelin bassist John Paul Jones is moving into the world of classical music by writing his own opera.

The musician is currently working on a stage show based on The Ghost Sonata by Swedish playwright August Strindberg, but admits the project is a daunting task.

Speaking to Red Carpet News after the London premier of Philip Glass' opera The Perfect American, Jones revealed his love for the genre, saying, "It's unlike anything else. It's the emotion, the passion... and I'm writing an opera myself so I have to say that."

The bassist is currently half-way through writing the first act, and when asked about the challenges of putting together an opera, he replied, "The sheer scale of it, I think. I'm probably about to find out what the challenges are."
