Ska years- book excerpt by Richie Unterberger and interview with the author
"There were some cool moments in their covers, but the Wailers' ultimate strength lay in their originals, at this point mostly composed and sung by Marley. Yet as strong as the first of those to catch on had been, a good number of the others were on the
callow and derivative side. Some of the songs remained quite indebted to slow, dreamy, mid-1950's doo wop."
There's also an extensive interview with Unterberger about Marley and the book.
