The Biffy boys have achieved number one with their new album Opposites - which was released last Monday.
The double album - the band's sixth - sold 75,000 in its first week and is their first record to top the charts.
The band - who played a tiny gig for us and War Child at the Borderline on the day Opposites was released - talked Radio X's John Kennedy through the record track by track.
