Whether you like it or not, there are things about the world that we cannot change. That includes relationships. Sometimes, a relationship is not what it was meant to be. That is what the song Blue on Black focuses on. It shows the singer lamenting about how his lover left him and ran away. This may be a sad moment, but it is also true that what is done can't be undone.
The song was originally released by the Kenny Wayne Shepherd Band in 1998. It was written by Shepherd along with Mark Selby and Tia Sillers. It became a huge hit, topping the Mainstream Rock Songs chart and winning the "Rock Track of the Year" award from Billboard.
It is an acoustic song and is a bit different from Metallica's usual fare. It is slower and has a bluesy feel to it. However, it still has the signature power metal that they are known for.
In 2019, the heavy metal band Five Finger Death Punch covered this song. It was featured on their album And Justice for None. The band has a large following and it's easy to see why they chose this song for their cover.
The lead vocalist of the band, Ivan Moody, has stated that this is one of his favorite songs and he enjoys performing it live. In addition, the band has a strong connection with military members and first responders and that was another reason why they decided to record it. The proceeds from this collaboration were donated to the Gary Sinise Foundation which primarily benefits veterans and first responders.
