There are actually three waves of ska. The original Jamaican form developed in the late 1950's and early 60's, a revival in England in the late 70's/early 80's, and a second, mainly American, revival in the mid to late 90's.
The general message (when it's not about something random like showers or pigeons) seems to be life has its downsides but we can still feel good about it.
there were 3 main types of ska trad, 2 tone and 3rd wave though there are some others
it is often mistaken that ska was derived from reggae
