Big K.R.I.T. is still down in Austin for SXSW, but this morning he finally let loose the mysterious artist who will appear on his Def Jam debut Live From The Underground. Appearing on Sway In The Morning on Shade 45, K.R.I.T. says the legendary B.B. King will appear on a single called “Praying Man.” Although K.R.I.T. hasn't dropped an audio for it yet, this song should be something special.
