I've never listened to this Valaska, so I couldn't say. Different reviewers is obviously a factor. I also feel it's kind of necessary to scale down the score for an EP a little. To score it high-80s, for example, would seem to imply that it accomplishes in five tracks what great albums do in ten. Without a doubt, though, the band is a lot of fun to listen to.
I agree 100%. Very well written review and I love BLK JKS. They had one of my AOTY's last year.
