On Saturday, VEVO is presenting Nas at ACL Live at The Moody Theater in Austin to close down the SXSW Music Festival. Nas is going to perform his entire Illmatic album backed by a full band for what should be a rare, epic performance of some classic hip-hop. Before the show, VEVO caught up with the veteran MC to revisit a couple gems from his debut. Hear him talk about the inspiration behind "Halftime" and "One Love" in these two clips.
