There are two things in rock n' roll that can't be killed: Keith Richards and Dave Grohl's enthusiasm. Despite breaking his leg last month, he remains as positive as ever, saying that his condition has brought an entirely new dimension to Foo Fighters concerts.

“The shows we’ve been doing lately are our favorite shows that we’ve ever done,” Grohl revealed to Entertainment Weekly. “What seemed like a setback at the time has turned into this beautiful blessing in disguise, where this throne and these crutches and these audiences make us play longer and harder than we ever have. It’s this whole new energy in the show.”

He explains that the throne was necessary because, with a major gig set for Washington, D.C.'s RFK Stadium on July 4 in honor of the 20th anniversary of their debut, he couldn't "just sit on a stool like Paul Simon.” While recuperating from surgery -- and, by his admission, whacked out on painkillers -- he came up with the idea for the throne.

It was different because, throughout the Foo Fighters' history, they "never relied on any kind of production at all. We usually just put the amps on the stage, turn on the lights, and play. Now we’ve got this throne that shoots lights and smoke out of it and looks like a f---king UFO with guitar necks stuck in it.”

And as he told Rolling Stone yesterday, the extent of his injuries -- a broken fibula, a dislocated ankle and ligament and cartilage damage -- "could have been a lot worse [...] The shows are the easiest part of my whole day. The rest of the time, I'm hobbling around trying to brush my teeth and pack my bags and walk down the street and get a cup of coffee. The challenge is the other 21 hours of the day. But I'm good. I'm just taking it one day at a time."

Grohl has even worked his immobility into his music. Rolling Stone found the above video of him beginning the guitar solo to "Outside" by running the neck of his guitar back-and-forth on his cast.
