Nearly every Bob Marley song is in some way political; these funky, rootsy reggae jams are just the most explicitly so. Tracks like "Get Up, Stand Up" speak as much with their music as their lyrics, urging solidarity over a distorted bass catchy enough to inspire it. And on the R&B-influenced "Ambush in the Night", the personal and the political combine when Marley connects a failed attempt on his life to colonial subversion.
