(Cover) - EN Showbiz - Dave Grohl claims the Foo Fighters "used to suck".

The legendary rocker admits his band has got better at live shows over time. The Foo Fighters performed a headline set at the Reading and Leeds UK music festivals that took place over the weekend and Dave is thrilled with how much they have improved.

"We used to suck," Dave revealed to NME magazine, "but now we are pretty good."

The alternative rock band are renowned for their lengthy shows and always aim to put on a performance that people will remember. They even use effects such as fireworks to give the crowd more value for money.

"We don't do those little shows," Dave continued. "We do those big shows, where everybody goes home saying, 'I can't believe they played that many f**king songs.'"

Foo Fighters take every show as seriously as when they first started out. Dave previously enjoyed success with grunge group Nirvana and never expected his next outfit to become so successful.

"Like any band we didn't expect to be playing to an audience this big. It's a big f**king deal," Dave explained. "You don't need a computer, you don't need to finish high school, you just need to pick up a guitar and start a band. I'd like to say thank you for the past 20 years of my life." (C) Cover Media
