Two of the biggest rock acts on the planet have unveiled brand new music videos.

Arcade Fire's fourth album Reflektor hasn't quite hit the heights of The Suburbs or Funeral before that. We'd place it somewhere in the neighbourhood of Neon Bible if we were to evaluate the band's discography.

That said, Reflektor still has a handful of fantastic tunes and chief among those is the excellent 'You Already Know' - the fourth track to be lifted from the record. And yes, the first voice you hear on the song *IS* Jonathan Ross. Check the video below.

Supermodel Lara Stone is among the cast of the new Black Keys video for the songs 'Weight of Love' from the Ohioan band's latest album Turn Blue. Stone plays the leader of a cult-like group who have a wanton disregard for clothes at various points throughout the clip. You have been warned.
