Both jazz giants in their own right, the collaboration between Ella Fitzgerald and Louis Armstrong was, predictably, the stuff of legend. After dabbling with informal recordings years earlier, Fitzgerald and Armstrong released their first official album of duets, Ella and Louis, in 1956. Her sweet, pitch-perfect singing blended effortlessly with Armstrong’s deeper, raspier vocals. One year later, they followed up their debut effort with Ella and Louis Again, which saw the performers sing solos, and in 1958, their third and final album, Porgy and Bess, was released. The latter, a compilation of songs from the Gershwin opera of the same name, became their most famous collaboration and was inducted into the Grammy Hall of Fame in 2001.
