If I want to hear vocals I sit down and retrieve following albums from my collection because of how superbly they were recorded to bring out the vocals right upfront!
Tracy Chapman (first album no title)
Patricia Barber - Cafe Blue
Eleanor McEvoy - Yola
Ella and Louis - Porgy and Bess
Suzanne Vega - Solitue Standing
Diana Krall - Live in Paris
Natalie Cole - Unforgetable
There are many but you can consider the above if you like.
