they've definitely changed their style a bit from their early work, a lot more experimental with their flows and raps. I ain't mad though, I fukk with their older stuff and newer stuff equally.
Most people would tell you
808s & Dark Grapes II, which probably would be the best place to start with them. They got some great production on this tape, and even though they're not the best lyricists, it's their best performance as a duo, and the hazy 'cloud' atmosphere really covers up any shortcomings pretty well. It's just an easy tape to vibe to.
Make sure to check out some of their earlier shyt, especially the tape
I Smoke Because I Dont Care About Death. Turn the bass up on this one, and every now and then, squadda will drop some real shyt in these tracks.
others to check:

I can hook anyone up with some links if they need em, just lemme know.
