Biffy Clyro's new album Ellipsis looks to be a dead cert for their second Number 1 album.
The Scottish group's seventh studio album is outselling the Top 5 combined as of today's chart update. The band's nearest rival is Adele - her third studio album 25, one of the UK's 30 biggest sellers of all-time is at 2.
Biffy's last studio album Opposites was their first to hit Number 1 in 2013. They previously hit the Top 5 twice before with 2007's Puzzle (2) and 2009's Only Revolutions (3). Look back at Biffy Clyro's complete UK singles and albums chart history here.
Finishing out the midweek Top 5 are Rick Astley, up five places with 50 (3), Coldplay's A Head Full of Dreams (4) and ELO's All Over The World (5).
