Rolling Stones Drop Long-Lost Track ‘Scarlet’ Featuring Jimmy Page: Find Out When the Video's Dropping

It’s not every day you get a new, old Rolling Stones track.

The Stones unearthed “Scarlet,” featuring Led Zeppelin guitar hero Jimmy Page and late bass great Rick Grech (Traffic, Blind Faith, Family) and recorded way back in October 1974.

Update: The group later announced that the official video will debut on Thursday (Aug. 6) at 7:00 p.m. BST, and will feature Emmy-nominated actor Paul Mescal (Normal People).

A "holy-grail" release from the rock veterans' golden age, “Scarlet” breaks out of the vault for the multi-format and deluxe reissue of Goats Head Soup, due to drop Sept. 4 via Universal Music Group.

“I remember first jamming this with Jimmy and Keith in Ronnie’s basement studio,” recounts Mick Jagger in a statement. “It was a great session.”

It’s a free-spirited blues-rock number with layered guitars and hooks galore.

On it, Jagger sings: “Scarlet, why you wearing my heart, on your sleeve/ Where it ain’t supposed to be/ Scarlet, why you tearing my heart, all to pieces, it ain’t the way it’s supposed to be/ Scarlet, why are you keeping my heart, to yourself, it ain’t the way it’s supposed to be.”

The rereleased special packages will feature 10 bonus tracks, including previously-unreleased track "All The Rage" and the recently-surfaced “Criss Cross.”

The Stones’ Keith Richards has his own recollections on how “Scarlet” took shape and how “we walked in at the end of a Zeppelin session. They were just leaving, and we were booked in next and I believe that Jimmy decided to stay.”

“Scarlet” was a freak accident. “We weren’t actually cutting it as a track,” enthuses Richards in a statement, “it was basically for a demo, a demonstration, you know, just to get the feel of it, but it came out well, with a line up like that, you know, we better use it.‘’
