I'm a little late to the party...but The Ella "songbooks" are simply outstanding. She is so polished and oh the ease of her singing is enthralling to me. I saw her at Radio City Musical Hall and she was one of the few artists that had the audience in rapt attention the entire time. Piano, bass, drum kit and that amazing voice.
The other was Frank at Madison Square Garden "The Main Event", you could hear a pin drop in the place. He had a big band/orchestra backing him up. Frank gets you with the phraseology/timing.
