the 1972 movie "the harder the come" helped create a new musical wave around the world. it featured the music of jamaica's musical stars, jimmy cliff [left, who also starred in the movie], the melodians, the maytals, and desmond dekker.

and even though he wasn't in the movie, the soundtrack kickstarted bob marley's [right] world-wide career, as many in the rock and pop scene began to broaden the range of their ears and discover reggae and a new culture, and marley and cliff were the most creative exponents going at the time.

all of this week's show features reggae music that was released 40 years ago. it was a remarkable year, and you'll be surprised at how much you've already heard. from the ubiquitous "i can see clearly now," to the original "rivers of babylon," and two versions of "the bigger they come." the songs are here: 1972 reggae.
