The album is being produced by St. Vincent and Sigur Rós collaborator John Congleton.

Sia, Charli XCX, Johnny Marr and Strokes’ guitarist Albert Hammond Jr have all written tracks for the new Blondie album.

Chatting to Charli XCX for her pre-recorded Beats 1 show The Candy Shop– which is due to air at 8pm tonight (May 6) – Blondie co-founder Chris Stein said that the tracks are all finished and Debbie Harry just “needs to sing more.”

Stein explained that the pair have invited a host of collaborators to write songs to write songs for the as-yet-untitled LP: “Sia and that guy from the Strokes wrote a song that we have on there,” he said. “Johnny Marr, we have a Johnny Marr track that we really like.”

Debbie Harry called the Sia track “amazing” and said “it lifts right into this chorus,” and also declared that she’d “love to have Ludacris” on the record.

Charli XCX has submitted two tracks for the record, which will also feature YouTube sensations The Gregory Brothers and Providence street band What Cheer? Brigade.

No release details have been shared yet about the new Blondie record, which is the follow-up to 2014’s Ghosts of Download.
