Judas Priest, one of the most influential heavy metal bands of our time, continues to wow legions of new and old, what frontman Rob Halford calls 'metal maniacs' alike.

You even hear a little homage to one of their pals, Rush, on the first track. We sat down with the 72-year-old force of metal remotely to hear all about it.
