In all due respect to The Roots, they don't have the same career arc or aims as OutKast. OutKast is world-famous and acclaimed on a level The Roots never sought or tried to claim. I hope this isn't meant to disparage the group because what the band has managed to carve out over the past thirty years is arguably harder than what OutKast managed to pull off.

Lil' Wayne or Jay-Z would have the hits needed to compete but neither MC's are groups (obviously) or have the diversity of musical and lyrical styles as OutKast.

Maybe the thing to do with Kast is to just bring in artists they've collaborated with or artists who have interesting stories about OutKast to come in and play songs.

Or have Big and Andre play their favorite songs that contain their favorite verses or bring up great memories.

I think that's what's been impressive about Versuz - just hearing the unheard stories and histories behind the groups.
