I've never quite gotten the whole idea that DMB and Steely Dan are somehow equivalent to each other. That DMB is the modern steely dan. I mean, DMB is so bland it's ridiculous. Basically, there are two great musicians (Carter, and to a lesser extent, Stefan) in DMB. The two soloists (LeRoi, and especially Boyd) don't cut it. Boyd's solos are all the same, and LeRoi sounds like a guy who tried to play jazz, but couldn't cut it, and got into DMB for some relief from the rigors of jazz. The DMB fans don't strike me as very musicianly. When they debate people who, for example, don't like Boyd playing out of tune all the time, they just say that Boyd runs around the stage a lot. They care more aboiut the spectacle of a big black dude playing the hell out a violin than they care about the music.
And witty lyrics? DMB? DMB puts out some of the most corny lyrics. One listen to "Rapunzel" is all you need to know that.
That being said, some of the DMB studio stuff is alright because they they cut down on the bland rambling, produce the hell out of Boyd and LeRoi, (pitch-correcting the former, drenching the latter with reverb), and they bring in guys who can actually play (like Tim Reynolds) to take solos.
But Carter is the man.
