The song was released in 1980, as a track from his "Legend" album.
Other famous songs produced by Marley includes "Exodus", "Jamming", and "One Love".
Emancipate yourselves from mental slavery, None but ourselves can free our minds
During a time of political, social, and economical upheaval for minorities, Marley expresses his belief that in order to truly escape from discrimination and "mental slavery", African Americans must believe that they are not inferior in order to gain proper independence.
Have no fear for atomic energy, 'Cause none of them can stop the time
The 1960's was a time of great tension where many were in constant fear of a nuclear attack during the Cold War. The verse from Marley exemplifies the understanding that in order to find peace within oneself, one should relieve their conscience of fears and insecurities.
How long shall they kill our prophets, While we stand aside and look?
Marley may refer to many people with this quote, but it is implied that the audience understands the assassinations of Martin Luther King Jr. and other important figures like Malcolm X. The use of rhetoric is employed by Marley to communicate the idea that the minorities need to voice their opinions and protest so that supremacists and racists do not murder their leaders.
"Redemption Song" was created by Marley to empower the black community and rally support or the protest against discrimination and racism, while implying that each person bears a responsibility, and that no one should stand idle and hope that others will sort out their problems.
