Bob Marley's Exodus Turns 40 (Billboard)

Bob Marley's Exodus Turns 40, a Billboard magazine feature from 2017, is a track by track fortieth anniversary review with production and thematic detail on the title track's Rastafari and Exodus typology. Its strength is that it is specialist music trade journalism from an established industry publication, close enough to the subject to add production detail beyond a bare encyclopedia entry. Its limit is that it is magazine journalism rather than scholarly analysis, and the atlas has not been able to re-verify the page directly against Billboard's own site, which currently refuses automated access; a claim resting on it should also be checked against another independent source where one is available.
