The Skinny: Judas Priest’s headlining performance on Saturday, October 24, 2015 was the pinnacle of Knotfest 2015, and arguably the best showing of the whole event. The heavy metal veterans unleashed a set of their greatest cuts, including a couple from their 2014 release, Redeemer. The metal gods more than merited their spot on the Knotfest bill and made a lot of the bands who played this year look like amateurs.
