Radiohead appears to be putting the finishing touches on their ninth studio album. On Tuesday, longtime producer Nigel Godrich tweeted a photo of lead guitarist Johnny Greenwood at the mixing board with a cheeky ode to fashionista Anna Wintour.

The U.K. group began recording their follow-up to 2011’s “The King of Limbs” last year.

“We worked throughout the autumn up to just before Christmas,” drummer Phil Selway said before the band returned to the studio in March.

A spokesman for Radiohead was not available to comment.

It’s unclear when or how they will release the new material.

Their last two efforts, “In Rainbows” and “King of Limbs,” were self-distributed and released online without notice. In recent years, high-profile artists like Beyonce and Drake have adopted this ‘surprise’ album strategy as the music industry continues to adapt to the digital era.

Frontman Thom Yorke and other Radiohead band members have kept busy with various solo projects in recent months. Yorke released an eight-track record on Bit Torrent last year, Greenwood scored Paul Thomas Anderson’s “Inherent Vice” and Selway issued a solo album in October.
