The band shared the photos from recording sessions with the caption, "Making metal on ‪#‎metalmonday‬!! @robhalfordlegacy @falconfaulkner ‪#‎glenntipton‬ ‪#‎judaspriest‬‪ #‎priestfamily‬."

Frontman Rob Halford recently said the band aimed to release their 18th album in 2017, adding: "I can't wait to get into the writing zone again - that's one of the most thrilling moments for me in Priest.

"You go into a room with some amps, 'Hey, guys, have a cup of tea,' turn the amps on, start riffing, and boom - you could have another amazing Priest song by the end of the day.
