"She warbles like a bird in the uppermost regions, hoots like an owl in the lowest registers and produces bell-like coloratura passages . . ."

Yma Sumac, the Peruvian-born singer whose spectacular multi-octave vocal range and exotic persona made her an international sensation in the 1950s, has died. She was 86.

Bursting onto the U.S. music scene after signing with Capitol Records in 1950, the raven-haired Sumac was known as the "Nightingale of the Andes," the "Peruvian Songbird" and a "singing marvel" with a 4 1/2 -octave (she said five-octave) voice.

"She is five singers in one," boasted her then-husband Moises Vivanco, a composer-arranger, in a 1951 interview with the Associated Press. "Never in 2,000 years has there been another voice like hers."
