After teasing it for a week, Sum 41 are back and have dropped their brand new single 'Out For Blood'.
This marks the first new music we've seen from the lads since the release of their 2016 album '13 Voices', and it's just what you want from new Sum 41 music - it's fast, it's aggressive, it's pop-punk. It's pretty great.
As yet there's been no official word as to whether this is leading into a new album - but we have our fingers crossed.
