According to rollingstone.com, Roger Waters' opera is long-awaited:
"Former Pink Floyd leader Roger Waters has completed Ca Ira, his long-awaited opera. After a decade of work on the project, Waters reports that 'it's done and delivered' and should be available as a double-CD through Sony Classical this fall. Ca Ira -- loosely translated as 'So It Will Be' -- was inspired by the French Revolution [like Les Mis! -JH] and is the latest conceptual work from the mastermind of The Dark Side of the Moon (1973) and The Wall (1979). Waters is considering staging Ca Ira as a concert performance in Rome this November with a full symphony, as well as adult and children's choruses. 'I might conduct it,' he says. 'Wouldn't that be a buzz? Of course, I might need a few beta blockers before going on.'"
Oh, those rock stars and their drugs.
