C&A:

The first four bars of Charlie Christian’s solo on this alternate take of Profoundly Blue begin with the same ideas as on the master, then the solo takes an entirely different path.  At the fifth bar on the master take, he goes to even lower notes;  here he suddenly leaps way up to the higher frets.  On mm 2 of the third chorus, Charles plays the same double stop and line that he played on mm 6 of the third chorus on the master take but with a different resolution—it’s a common phrase of his that he’s just as liable to play over Ab7 or Bb7 as he is on the Eb in this key.

His solo on this take may be just as good as the master but it’s difficult for me to pass judgment—I played the master for many years before the alternate was finally released.  The excellent solo on this take also has a lot of great blues lines with slurs, bends, and slides but the master remains my sentimental favorite.
