Reaction - "Tumpa" (1954) - The Amazing Yma Sumac 

The one-and-only Yma Sumac in a spectacular number from Secret of the Incas, a 1954 movie that presumably has a plot that mainly serves to show off her amazing voice. This is a short clip but in it you can get a sense of her immense range. (Trivia: Sumac won a Guinness World Record for the Greatest Range of Musical Value in 1956.)
