Punkfolkrocker I think you would enjoy listening to more of Lankum who won the Best Group category. Both their current album and their previous one under the name Lynched. Here they are live doing a more uptempo song from their current album. They are also shown quite a bit on the series "This Aint No Disco" which shows that they seem to be quite far from the middle-class stereotype that folk are throwing about concerning modern bands.

Likewise I really like The Young'uns. Who won the best album category and are maybe not all that young but can sing a bit.
