seeing the Dolls on Kimmel was admittedly odd. JK, by virtue of its post-midnight timeslot, does have a lot of latitude in booking its musical acts. still, the show is dominated with a decidedly frat-boy aesthetic so usually that latitude is enforced by bringing in stuff more along the lines of Atreyu or Matisyahu. The Dolls don't really seem to fit the mold. I commend Jimmy's crew for painting outside the lines on this one. (This is, of course, ignoring the possibility that Disney and the Dolls' label have an established marketing tie, making the Kimmel show's decision for it.)
I'm not so sure about the Dolls' choice (whether it was theirs or by fiat) of song. Backstabber doesn't stand out in particular to me. Truth be told, to my ears, it only holds the title of "Second Best Song Named 'Backstabber' by a Boston-based Band"; the winner of course being Thumper's unbeatable song of the same name. Apparently, backstabbing in Beantown is an offense liable to get you written up in verse. From what I've been able to hear here and there, there are much better song candidates for national exposure available on "Yes Virginia".
But hey, no ones asking me.
