A residential recording studio in Wales that was a favorite spot for Black Sabbath is up for sale for $2.45 million.

The studio space is called the Old Mill House, and it was part of the Rockfield Studios complex.

Owner Jo Riou said of the studio, “I have been told that behind all the sound proofing on the walls is where Ozzy Osbourne drew pentagrams on the walls. I was told that Jimmy Page had drawn a mural on the wall too.”

She added, “So when someone buys the house and if they don’t want this room as a studio, they could strip it out and God only knows what they will find!”
