Lindsey Buckingham and Mick Fleetwood Reunite for the First Time in 7 Years During Studio Session

Lindsey Buckingham and Mick Fleetwood are back in the studio together.

The former guitarist and drummer of Fleetwood Mac have reunited in a recording studio, per Swedish record producer Carl Falk.

“Slightly unreal moment to sit with Lindsey Buckingham and Mick Fleetwood to play Lindsey the album we have been working on,” Falk wrote in a Threads post dated Feb. 20 alongside a picture of Fleetwood, 77, and Buckingham, 75.

"And to see his genuine happiness for Mick to finally do his own album and offering to play guitar and to sing on it," Falk continued of Fleetwood's project. "Can’t wait to finish this one."

Weeks later, Falk shared another picture on Threads on March 16 of the two musicians standing outside, along with a video of Buckingham "jamming." "Mick and Lindsey together again, what a flawless guitar player," he said in another post shared the same day.

Other posts from Falk showed Fleetwood working with Adam Granduciel of The War on Drugs.

Further details regarding when Fleetwood's project could be released remain unclear.

The recent recording session marks the first time Buckingham and Fleetwood have reunited since the former was kicked out of Fleetwood Mac in 2018. Following an argument at a MusiCares performance about Buckingham working on a solo album while the band was set to go on tour.

"Mick knows I would come back like a shot," Buckingham told PEOPLE in 2021. "But I'm not hanging my hat on that at all."

"It was all Stevie's doing," he added of his former flame and bandmate Stevie Nicks. "Stevie basically gave the band an ultimatum that either I had to go or she would go. It would be like [Mick] Jagger saying, "Well, either Keith [Richards] has to go or I'm going to go.'"

Nicks, 76, meanwhile, said in a statement obtained by PEOPLE: "I did not demand he be fired. Frankly, I fired myself. I proactively removed myself from the band and a situation I considered to be toxic to my well-being. I was done. If the band went on without me, so be it."

Fleetwood Mac was formed in 1967 consisting of Fleetwood, John McVie and his then-wife, the late Christine McVie. Buckingham and Nicks joined in the 1970s. The group has won two Grammys among seven nominations throughout their careers.

The band last performed all together in 2018.
