"This is the story of America's greatest rock band," goes the narration that opens the new video for Aerosmith's "Legendary Child," the first single from their upcoming record, Music From Another Dimension. The narrator goes on to detail the band's exploits – good, bad, hilarious and some totally fictional – and promises the clip will tell the story of the group as played "by girls on roller skates." Indeed it does just that, though, in a Fincher-esque move, it looks like you're gonna have to stay tuned for the next chapter to see what's in the box.
