PBS tonight aired the first part of a two part series called “Latin Music USA” that gives a very good overview of not just salsa but all Latin music. Covering everything from Latin Jazz to Latin Pop, the series does an excellent job of explaining the roots and influences that created the wonderful music we all enjoy today.
The second part of the series airs on October 19th at 9pm ET/PT and if you missed the first part you can see it on the PBS website: http://www.pbs.org/wgbh/latinmusicusa/
Also check out the viewing guides, one in English and another in Spanish.
Thanks to PBS for putting together a great documentary!
