“These tapes” — of Fitzgerald’s return to Berlin two years after her 1960 debut there, a concert which became a Grammy-winning bestseller — “come from impresario and Verve Records founder Norman Granz’s private collection. As Ella’s manager, he had a habit of recording Ella live – sometimes for radio broadcast, sometimes for later release, sometimes just to have. He also had another habit of focusing on his next project rather than harnessing what he had just recorded, thus the tapes being lost.” – Glide Magazine
