Pig Destroyer played one of the outside, uncovered stages at the “former Sonar Compound,” and had a few guest vocalists come up and sing tracks from Book Burner with them, namely Jason Netherton from Misery Index and Katherine Katz. Later, Righteous Pigs played an ultra-rare set on the same stage. MDF staples Rotten Sound played the Sound Stage in Baltimore, a few minutes’ walk from Sonar.
