Broken Bells’ James Mercer
Mostly handling singing and keyboard duties for Bells, Mercer did pick up his beloved ’60s Les Paul Junior—the guitar he uses frequently when fronting the Shins—for parts of “The Ghost Inside.”

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.
