Dave Grohl is bored by the idea of simply recording an album in a studio.

The Foo Fighters frontman and his bandmates travelled to various cities in the US to record tracks for their new album 'Sonic Highways' - with the process captured in an accompanying TV series with the same name - and now he can't imagine returning to a straightforward recording process in the future.

He explained to Q magazine: ''Ultimately, this is one hell of a f**king machine that's gonna spray this album everywhere...But you have to balance that with substance.

''More than a reality show, more than a live concert series. It's part of the reason that we got deeper into the concept, because we would love people to learn as much as be entertained.

''But I can't imagine just going into a studio and making another record. It seems so boring to me.''

Dave recently explained the group explored the ''regional relevance of music'' while recording 'Sonic Highways'.

He said: ''Basically, the process is we come to a city and we spend a week and we start recording an instrumental, because I interview all of these different musicians from that city.

''I talk about the regional relevance of the music from that city, the cultural influence, that 'made-for-the-sound' of the music.

''There's no way that you can tell the history of a city's music in one hour, so we have to do it in a way that relates to the band and goes from point A to point B and becomes a song.''
