Nothing quite like good ol' fashion bar sharing between two MCs. I have written before about the roots of this type of exchange and how good it can sound when done well.There are a few artists that still get down like that here and there, although they don't do the harmonize rhyming old schoolers did.
Bad Meets Evil by Royce the 5'9" and Eminem has a few examples of this type of back and forth. One of my favorite tracks is A Kiss.
If you can get past the gratuitous misogyny and violence you'll see the that these two displayed real chemistry with their flow. They also managed to slip in lots of over-the-top humor on this solid beat.
