Earlier this month, Foo Fighters were forced to reschedule their New Orleans’ shows on February 15th and 16th at the grand opening of the Fillmore due to an injury. According to Billboard, Dave Grohl revealed why the group had to reschedule the dates to May 15th and 16th. During a conversation with Live Nation president and CEO Michael Rapino at the Pollstar live conference in Los Angeles, Grohl revealed he underwent surgery on his left arm.

He explained:

“This is something I’ve had to deal with for a long time and it’s not the end of the world but I did have to have surgery on my arm because I need it to pay the rent,” Grohl told the audience at the Beverly Hilton in California. “I knew I had to fix my arm at some point and I went ahead and did it. It’s funny having surgery because you actually get a little bit of rest. Right before they wheeled me in [for surgery] the guys said ‘hey, we’re going to give you something that’s going to make you feel really good’ and I thought I finally get to take a nap.”

Later, Grohl discussed why he loves touring:

“The excitement of seeing live music, of seeing people on stage, that will never go away. We don’t sell a tenth of the records that we sold 20 years ago, but we sell out fucking stadiums in a lot of places. One of the reasons is we’ve been touring for 20 years and we’ve never stopped. You have to establish a base and be faithful to them.”
