Relations between Southern and East Coast rap have often been tenuous, from the difficulties Southern artists had getting media coverage in rap's golden era on through last year’s Trinidad Jame$ vs. the City of New York tiff. OutKast extended the olive branch in 1998 with the Raekwon assisted “Skew It on the Bar-B.” It wasn't the first time a Southern group tapped an East Coast MC for a feature or vice versa, but it wasn't long after Aquemini’s release (and millions in sales) that we saw the Jay-Zs, Juveniles, Jermaine Dupris, and Ruff Ryders throwing down on tracks together.

It’s a domino effect that you can see the fruits of in today’s conversation between the Northeast and the South, evidenced by guys like French Montana and A$AP Rocky rolling down South sounds into New York rap as well as the great musical chemistry between NY champs like Jay-Z and Nas and Southern analogues like Scarface and Rick Ross. Meanwhile OutKast affiliate Killer Mike has found great success by teaming up with NY-based producer El-P.
