both toby and my son bradley are professionally trained vocalists. toby is a fan of striesand, i don't know if bradley is.
i think the reason she is bored with her own voice is because she is a boring singer. she is always on key and rhythm, but all her songs lack soul. sort of like a good cake without the frosting, something is missing.
anita o'day would be my choice for a female singer, still alive, that can light up the speakers.
