Pretty good - Rilo Kiley have a very listenable quality even during their least inspired, and while there's little on More Adventurous that's really striking (the exception - and it's a big one - is "Portions for Foxes", which is still too, too delightful...it's just everything that a pop song should be) it's still plenty engaging for all of its surprising modesty.
Also: when I trotted up to the counter with this cd in hand a couple of weeks ago, the record store girl glanced at the back of the cardboard slipcase and was moved to exclaim, of Jenny Lewis, "Hey, she's cute!"...which is, of course, perfectly and incontrovertibly true.
