The Gershwin songbook gave Ella Fitzgerald a set of melodies she could bend into anything.
I'd place this record among Ella Fitzgerald's essential Verve-era songbooks, the series that defined how a large audience would hear the Great American Songbook for decades. Coming after the Cole Porter and Duke Ellington volumes, it's a natural continuation of that project, and for many listeners it's the first place they encounter her interpretive control at full stretch. If you want one entry point into the songbook series, this is a strong candidate alongside the Ellington set.
The Gershwin material suits her well. Songs like "Someone to Watch Over Me" and "They Can't Take That Away from Me" give her room to phrase slowly and then push the rhythm forward with a clean, confident swing. Her diction is precise without being fussy, and she rarely sounds like she's showing off, even when the scatting and vocal runs are at their most dazzling. The arrangements, handled by Nelson Riddle in the orchestral context, keep the backing supportive rather than overwhelming, which lets the voice carry the melodic shape of the tunes.
The record was well received when it appeared, and critics have generally treated it as one of the stronger entries in the series. It isn't the most adventurous album in her catalogue, but it does exactly what it sets out to do: it makes a body of classic songs feel fresh, and it shows why Fitzgerald became the default interpreter of this repertoire for so many listeners.
