Biffy Clyro have released a new video for the first track 'Stingin' Belle' off their forthcoming double album Opposites.

The single will be released on September 17.

The lads look like they're on flying form, laughing, messing and just being general band eejits in their new video, and the tune is pretty rocking too. Check it out...

[ed's note, we got our celtic cousins temporarily confused earlier and called the Ayrshire natives Welsh! ]
