Samuel Martins Alves (born June 3, 1989) is a Brazilian singer, who participated in the blind auditions of the fourth season of The Voice (U.S.), singing "Feeling Good", classic in the voice of Nina Simone. The four coaches (judges) showed they were enjoying it, but none of them pressed the button to choose him.
In December 2013, Sam won the second season of The Voice Brasil (Brazil), and signed with Universal Music Brasil.
When he was only two days old, Sam was abandoned in a shoebox at the door of a house in Fortaleza, Ceará. With him, a note written with some writing errors said that he was born on June 3, 1989 and given porridge at 3:00 on June 5, the same day Luiz and Raquel Alves found him. The boy had just turned four when his family decided to move to the United States. The young man grew up and was educated in Massachusetts. His father was a pastor and had done some newspaper delivery routes to make a living. His mother Raquel cleaned houses for a living.
