Broken Base: Triggered by Butch Taylor's departure from the band on the eve of the 2008 tour and Tim Reynolds coming in as his replacement, resulting in the band's shift from a jazz-centered sound to a more rock-oriented one.
Narm: Everything on Stand Up, for sounding so completely out-of-character.
Replacement Scrappy: Jeff Coffin (who replaced LeRoi Moore on sax after the latter's tragic death) mostly manages to avert this among reasonable fans. It doesn't hurt that he used to be a member of Béla Fleck and the Flecktones, who have opened for Dave Matthews Band on several tours.
Signature Song: "Ants Marching" and "Crash into Me" are probably their best known songs from a commercial standpoint.
Snark Bait: They're a common butt of jokes about toothless yuppie music.
