In an exclusive interview given to "Brave Words & Bloody Knuckles", Judas Priest guitarist K.K. Downing revealed some details about the quintet's upcoming concept album about the life and predictions of 16th century French prophet Nostradamus:

"Rob Halford has already put vocals down on some of tracks, but they've only been kind of roughed out.
"The music is running an hour and 39 minutes at the moment. It's looking that we'll have two CDs. I think there is one idea that we can afford to leave off, but the rest is still going to run about an hour and a half.
"There are 18 songs, but there are a lot of links between them. There are many instrumental parts, so it's a full-on musical really. There's also going to be orchestrations. It's all myself and Glenn Tipton putting it together.
"Nostradamus" will be definitely out by the summer."
