From Adam Lopardo:
"am at @johnrobb77 talk about The Art of Darkness. Said he was at Rockfield Studios 2 weeks ago and asked staff about @thecure album. Apparently It’s finished but @RobertSmith keeps tinkering cos he’s a control freak. They said it sounds amazing. One day we’ll hear it!"
Have heard that from other people too. And that this isn't a new development. "Done", but Robert won't let it go. Reeves mentioned it too in a recent interview.
