Summer might not be official yet, but May has given the season its first great rap jam. "Live from the Underground" is the title track of Big K.R.I.T.'s stellar debut album, which is streaming online now. The track is classic Southern rap - it has a smooth, leisurely feel, as well as strong notes of blues and gospel that showcase K.R.I.T.'s skill as rapper and producer. Go windows down and let his sharp, clever rhymes punctuate every slow-burning beat.
