Neither of the following released their debuts in the 2010s, but but were active throughout and released a bunch of good stuff (especially the former):
Rolo Tomassi
Blood Red Shoes
I guess you wouldn’t call Let’s Eat Grandma or Sleaford Mods “groups”?
Edit - just seen Sleaford Mods mentioned and I actually voted in the poll lol. Yes, they are definitely a great English group of the 2010s!
