This was the second album pairing Ella Fitzgerald and Louis Armstrong produced by Norman Granz for his Verve label. After recording a series of duets in the late 1940s for the Decca label, they were summoned by Granz in 1956 to make a series of sessions which would result in the memorable Ella and Louis. Such was the success of the LP, that the formula was repeated the following year with the making of 'Ella and Louis Again'.
