A style of early Jamaican music combining elements of mento (a form of calypso) with American jazz and R&B. A precursor of rock steady and reggae.
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 Skatalites are the oldest ska band still playing music today.
