Second rap group to have a rap record?

I think Sugar Hill Gang.

N.w.a

a group of rappers that work together such as La Coka Nostra, Wu-tang Clan, Ruff Ryders, and so on.

Run DMC

Shady the greatest of all time? That's ridiculous. But yes, 2pac has sold the most records ever. Even when 2Pac was alive, he was the best selling rapper. Eminem is second.
