Chicago’s other 3-day festival hosts an eclectic group of artists that span all of pop music.

Gwar’s Pustulus Maximus

The band’s newest guitarist Brent Purgason slays on his signature Blakhart model, the Whargoul Pustulus Maximus. Even though the guitar takes a beating every night, Purgason says he’s only had to make minor adjustments. His guitars are strung with .010-.046 D’Addario sets.
