Remember those lovable goofballs from 1995's Big Me video? Go hunt them down on YouTube - there's so much to enjoy: Dave Grohl rocking pigtails, Pat Smear's cheesy grin, and the rest of the Foo Fighters wearing matching tracksuits, acting like clowns and eating oh-so ironic "Footos" fresh mints.

It's hard to believe the same band is behind Sonic Highways, the new Foos record that comes with one hell of a grand idea: eight songs recorded in eight cities, with Grohl's lyrics inspired by interviews for an HBO series documenting the process. Even Barack Obama gets a look-in on what may be the biggest concept album ever created - one that's at complete odds with the claustrophobic intensity of 2011's Wasting Light, recorded in Grohl's garage. There's no faulting Grohl's desire to pull something like this off.
Eight albums in, the last thing anyone wants is another box-ticking record like 2007's Echoes, Silence, Patience & Grace.
They're challenging themselves, and the results lead to some great moments: Grohl's searing scream piercing through the riotous finale of Something From Nothing; the punk-rock eruption of The Feast and the Famine destined to be a highlight when it echoes around Mt Smart Stadium next February; and In the Clear's chugging symphony that turns into one of those great All My Life-style Foos anthems.
