The collaborations between Ella Fitzgerald and Louis Armstrong have attracted much attention over the years. The artists were both widely known icons not just in the areas of big band, jazz, and swing music but across 20th century popular music in general. The two African-American musicians produced three official releases together in Ella and Louis (1956), Ella and Louis Again (1957), and Porgy and Bess (1959). Each release earned both commercial and critical success. As well, tracks related to those albums have also appeared in various forms in multi-artist collections and other such records.
In terms of touring performances, Fitzgerald once again teamed up with Armstrong, after the success of their first album, to hold a series of concerts at the Hollywood Bowl. The duo's music proved popular with the live audiences.[1] Two live tracks from those 1956 concerts would end up being released as album bonus material in the 1990s.[2]
