In Winston-Salem, The Sound of My Voice is showing only through Thursday. Evening shows today at 6:30, Thursday at 9:00. It's at the a/perture theater downtown.
I saw her at one of her last shows, at Merlefest, with the large mariachi group Los Camperos di Nati Cano. 2009. Her voice was strong, with maybe a slight loss of pitch at times. I believe that she was a perfectionist, and perhaps quit before the vast majority of her fans would have noticed a decline.
I thoroughly enjoyed the show. There must have been at least thirty members counting the fabulous dancers in their traditional dress. The ladies full length Jalisco dresses were both colorful and mesmerizing.
Man, if your Mom made you wear that color when you were a baby, and you're still wearing it, it's time to grow up!
