Query: A tepid voice.

I was never very impressed with this album. Gloria Estefan's voice is soft and laid back, pretty, and best suited for easy listening classics, like the ones sung by Frank Sinatra, Nat King Cole, Vikki Carr and Eydie Gorme. Although she's Cuban, her singing isn't well-suited for Cuban music. Sorry Gloria, you'd sound better singing something smoother, calmer, where the listener isn't expecting a fiery, deeply passionate performance. Fire, that's it, that's what's missing in her voice.Cuban music = fire, passion. Mi Tierra = a brook.
