During the late '50s, Ella Fitzgerald continued her Song Book records with Sings the George and Ira Gershwin Song Book, releasing a series of albums featuring 59 songs written by George and Ira Gershwin. Those songs, plus alternate takes, were combined on a four-disc box set, Sings the George and Ira ershwin Song Book, in 1998. These performances are easily among Fitzgerald's very best, and for any serious fan, this is the ideal place to acquire the recordings, since the sound and presentation are equally classy and impressive.
