well, considering pharcydes heydey came and went fairly quick... i have to disagree with you. every song is hot? every last one? i havent heard them all, but i HIGHLY doubt that. there isnt one artist who has never made a song that saw the light of day and shouldnt have. anyhow....
i would make a vote here for outkast. why lets see.....
how many artist consistently get better as they go, with EACH album?
they went from southernplayalistic to atliens to aquemini without a hitch, getting better with each one, maintaining thier own signiture style while experimenting and expanding as they went, with mostly good results. i wasnt a huge fan of stankonia, but this album catipulted them into the stratosphere of superstardom.... and look at the differences in their hits!
how do you go from elevators and jazzybelle to rosa parks and da art of storytellin to ms jackson and bombs over baghdad? i mean they can do uptempo club songs equally as well as they can do the deep, "marinatin'" type tracks (remember 13th floor anyone?) and how many other groups can say that they can do both equally well? wu tang has tried and failed MISERABLY. tribe called quest is great as well, .....
and then we have the roots. damn, what, 5 albums now? they also have changed up their style very much with each outing and have really taken hip hop to some places that it hadnt been without them. no other group is as skilled musically, hell i will go out on a limb and say that they are more skillful musicians then most groups around, PERIOD. rock, jazz, whatever. these guys are REAL musicians, and you put them behind any artist and that artist becomes many times more interesting then he is otherwise. they absolutley KILLED unplugged for anyone else who wants to try it! no one has had a better unplugged performance (nirvana being the only equal in my view)... plus you look at their consistancy. they have had moments that werent the best but they are always solid and many times great. i would venture to say that they could even make chingy listenable to MY ears! so my pick would be a toss up between outkast and the roots, the roots having the edge in my book.
