Jimmy Page was photographed playing a guitar with his seventies live rig at Abbey Road Studios in London recently — and it’s unclear what it’s about.

Page’s daughter Scarlet Page published a photo to her Instagram account on November 18 which showed Page playing a black Gibson Les Paul guitar in Abbey Road Studios.

“Thursday’s shoot, a very exciting day at @abbeyroadstudios photographing the 70’s live rig with @jimmypage,” she wrote. She also included the hashtag “#theremin” and one commenter in the Royal Orleans forum pointed out a possible violin bow on the amp in the top left of the photo.

It’s unclear what the photo shoot was for, however a music producer friend of Jimmy Page claimed on Facebook that he spent two days recording with Page at Abbey Road Studios.

“I feel so lucky,” wrote producer Perry Margouleff on Facebook on November 17. “I spent two days recording in studio 2 at abbey road the room is great and the staff was fantastic.”

Margouleff posted that caption with the same photograph of Jimmy Page taken by his daughter Scarlet at Abbey Road Studios.

In the comments on the post, someone asked “Did he fire it up?” referring to Page’s guitar. “Yes we were recording,” Margouleff replied.

Jimmy Page has known Margouleff for some time, and it’s believed that Margouleff played a crucial role in reuniting Page with his stolen “Black Beauty” guitar. Margouleff accompanied Page and his girlfriend Scarlett Sabet to a Pink Floyd exhibition in London last year.
