Yesterday we got to see Nas perform "Daughters" on the Late Show with David Letterman. Last night he kept the promotional ball rolling for his recently released studio album, Life is Good, with a visit to The Colbert Report. Stephen and Nas sit down for a chat before Nas performs a rip-roaring rendition of "The Don". Peep the interview at the top and the performance after the jump, both courtesy of The Audio Perv.
