The Avett Brothers’ Bob Crawford
Crawford switched between his 1950 American Standard Upright and a newer Fender Precision bass during most of the Avett’s show. The St. Jude sticker on his electric is to help promote awareness of the cause and work done by the hospital—his daughter is battling cancer and had a brain tumor removed a few years ago.

This year marks Lollapalooza’s 10th year as a destination festival—its 18th overall—in Chicago’s beautiful Grant Park alongside Lake Michigan. Since its inception, Lolla has tried to serve all music fans with a healthy dose of rock, metal, punk, pop, dance, comedy, and hip hop acts. This year was no different with sets from Outkast, Eminem, Kings of Leon, Arctic Monkeys, Interpol, AFI, Cage the Elephant, and hundreds more. Premier Guitar was onsite for all three days and here are just some of the guitar-centric highlights from the event.
