The Bob Marley song "Slogans" is remarkable not only because it's a previously unreleased single. Thought to be recorded in a Miami bedroom in '79, the song was recently remastered by Marley's sons Stephen and Ziggy with a new guitar track by Eric Clapton. Available online for a limited time, the video of the song intercuts concert footage with images from hurricane Katrina, the toppling of the Berlin wall, MLK at a civil rights march, and other footage of barriers being challenged or ripped down. The lyrics are apropos for 2005: "Can't take your slogans no more. No more sweet-talking from the hypocrites."
