In honor of Martin Luther King, Jr. Day, Alicia Keys celebrates strong and courageous men and women on her previously unreleased song “Power.” The “Superwoman” searches within to find her strength on the empowering record, which she recorded in 2007 and just released on her website The Vault.

“This is one of my favorite unreleased songs,” said Alicia. “I was looking for my power. This song says it all. All of these pics inspire me! They represent the power of being yourself and finding yourself! Shine on!”

March to Alicia’s victorious anthem.
