Ella Fitzgerald ascended to jazz royalty with her pitch-perfect renditions of "A-Tisket, A-Tasket," "Summertime," and tunes from the Great American Songbook. Now, Verve Records plans to release a Fitzgerald recording from the 1950s that’s never been heard by fans. As WBGO reports, Ella at Zardi’s will make its public debut on December 1 after 60 years in the record label’s vault.

Fitzgerald sang the two sets featured on the album in 1956 after signing with Verve Records, a label her manager Norman Granz formed specifically for her. She was days away from recording Ella Fitzgerald Sings the Cole Porter Song Book, a turning point in her career, and she spent her nights practicing songs at Zardi’s Jazzland in Hollywood. The recording opens with Granz introducing Fitzgerald, describing her as “the greatest there is,” before she dives into her performance of “It All Depends on You.” The new release will mark the first appearance of the song on a Fitzgerald album.

After Verve recorded the sets at Zardi’s on February 2, 1956, they stowed the tapes away in the vault, where they lay buried for decades. The decision to finally share the music with the public comes on the year of the singer’s centennial celebration, marking what would have been her 100th birthday.

The full 21-track album will be available digitally and as an audio CD when it comes out at the beginning of next month. Listeners can preorder it today on Amazon.
