Are you talking about the newer albums or the older ones? On "It's a Jungle in Here," and "Friday Afternoon the Universe," they really rip the songs apart. I'd never call those albums boring. In fact, Jungle has some of the most reckless dissection of songs that I've ever heard. Their version of Coltrane's "Sveeda's Song Flute" is insane.
Having said that, the newer albums ARE somewhat boring and plodding. I think End of World Party is better...although it's an exercise in subtlety. They seem to be trying to do stuff that's more delicate these days. That seems to be the cycle that all jazz musicians go through.
As for their live shows...I saw them in Pittsburgh and it was awesome. The loudest most pyschedelic jazz show I've ever seen. But, that was about 3-4 years ago, before they entered their downer phase...
