I have a decent amount of Ella and admittedly don't listen to her often. Still, there is some quality about her singing - especially on the live stuff - that brings tears to my eyes when I least expect it. Also, from a technical standpoint, it seems that on the live stuff she's able to sound both raspy and crystal clear simultaneously, and the more she goes, the better her voice gets. Someone said earlier that her interpretations of ballads lacked, but I think select ballads of hers, such as "Get Out of Town," "So in Love" and "Isn't it a Pity," are very moving and heartfelt. And I wish she was paired with better arrangers on the Cole Porter and Rodgers and Hart songbook albums.
