All Saints, "Flashback" (2006)

In one way of telling the story, Big Beat came and went faster than you can say "Fatboy Slim." In another narrative, it, like many other genres of music -- much as matter is neither created nor destroyed -- simply stayed around in other forms. "Flashback," the second best song on All Saints' comeback album Studio 1, employs a big, brassy backing track that recalls in equal amounts the glory days of Chemical Brothers and, appropriately enough, given the song's title, big band jazz. But then again, the similarity was probably there all along; the booty-shaking that is the natural response to both just punctuates it.
