The Scottish rockers have been teasing their return over the past week through a series of cyan headers and display pictures and postcards sent to fans, which includes a link to a mysterious site with a handwritten note.

Today (17 February), Biffy Clyro have finally shared a 30-second teaser clip, which sees the trio paint a blue line across a sheet of glass to cover their faces.

Biffy Clyro captioned the clip: "INSTANT HISTORY #thisisthesoundthatwemake", which is also written on the site they linked to in their fan postcards.

The band are yet to confirm details of their follow up to 2016's Ellipsis. In October 2019, Biffy Clyro revealed they were planning to release the new album in the first half of 2020.

Although they haven't released a new album since 2016, Biffy Clyro haven't exactly been quiet - they released their Balance, Not Symmetry film score last year, and contributed a cover of Frightened Rabbit's "The Modern Leper" to their Tiny Changes - A Celebration of The Midnight Organ Fight album.

Biffy Clyro are yet to confirm new music. They play BBC Radio 1's Big Weekend in Dundee this May. Find out more.
