Foo Fighters Tour 2014: A few months ago, fans in Richmond, Virginia petitioned for the band to play in their town. A few months later, the Foo Fighters somehow gave the fans what they were asking for after the band played a surprise show in Washington DC last May 5.

At a 9.30 club in DC, a billed "special guest" was seen in the club and later that night, Grohl and the rest of the Foo Fighters went on stage to perform a 20-song long set for the shocked fans. The band played hits such as Times Like These, My Hero, All My Life and even Everlong, among others.

The surprise, however, didn't stop there. A few days later, Dave Grohl made as surprise show for a small group of 100 people for a surprise acoustic show in Bluebird Cafe in Nashville, as reported by Spin.

The former Nirvana drummer introduced himself "My name's Dave Grohl. I'm a drummer" during his set, while being filmed by camera crew, which suggests that the band might be doing something in lieu of their new album.

He played songs such as "Times Like These", "Everlong" and even "My Hero" among others and reportedly posed with fans for pictures after the show.

Meanwhile, while the Foo Fighters Tour is on the way, the band is reportedly half way through their new album, who is produced by "Wasting Light" and Nirvana's "Nevermind" producer, Butch Vig.

Speaking to Kerrang!, he said: "We've been recording at some different locations, but we're almost halfway done with the recording and it's going well.

"It sounds different - we've thrown a few things into the mix, in the recording process, that are going to give the record a different sound and a different feel. It's been a challenge, but it's also been exciting."

In an interview of the band in Rolling Stones, Foo Fighters front man Dave Grohl pointed out that the new album of the Foo Fighters would be something different that would surely surprise fans.

"It's badass. We're doing something that nobody knows about, it's f---ing rad. We're doing it in a way that no one's done before and we're writing the album in a way that I don't think has been done before."
