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

Modest Mouse’s Isaac Brock

The fiery frontman played a good chunk of the festival’s last set Sunday night with his Wicks Custom 6-string that has a solid mahogany body, a five-piece maple neck, a “Tree of Life” inlay on the pau ferro fretboard, a custom-made Calaham trem, and Wolftone pickups.
