A high moment listening to Ima Sumac. The voice has all the richness, beauty, and range of a mythical woman. It does not seem humanly credible. She sings like a siren, a bird, an angel, some seductive chant never heard before, high and low, fragile and strong. With all that, she has the exotic beauty of a legendary figure. I could imagine her in Peru, but not accept that she is married to a composer and now sings his Hollywood-type arrangements in a night club.
