It was the first of two collaborations captured for television. It was recorded for one of a series of live television sessions recording the performances of various artists. The show was called In Session. The album includes a few short segments of the banter by King and Vaughan between songs.
Initially, King was not going to do the show as he did not know who Vaughan was. He did not realize that Vaughan was actually 'little Stevie', the 'skinny kid' that he let sit in when King played in Texas. King talks about this on one of the conversation tracks. When he realized who Vaughan was, he agreed to play.
The album's material is mostly King's concert line up, with one Vaughan cut, "Pride and Joy." King is 'driving' the session, but he purposefully features Vaughan on a number of the songs.
