That clean, clear, flexible, and soulful voice can only belong to "The Queen of Song," Ella Fitzgerald. She amazes us with her improvising, range, and pristine intonation sounding like a trumpet at times. And she makes us laugh out loud when she scats, sounding like she knows something we don’t. But above all, Ella sounds like a lady, and one of the greatest jazz performers of any kind, of any time. You voted her the No. 2 Most Essential Jazz Artist.
