Ella Fitzgerald / Ella & Louis

The collaboration between jazz icons Ella Fitzgerald and Louis Armstrong is one of the most celebrated in music history, defined by the "silky" clarity of Ella's vocals paired with the "gravelly" warmth of Louis's voice and trumpet. While they first recorded together in 1946 for Decca, their most influential work was a trio of albums produced by Norman Granz for Verve Records in the late 1950s.
