ska, a fast upbeat music, the polar opposite of emo, fast dub reggae guitar strokes, quick drums, rockin bassline, and biting horn thrown in, all started by a man by the name of laurel aitken. Three different kinds of ska exist. Traditional, two tone, and third wave. Traditional is the stuff that came out of jamaica as dance music. Two tone was named that for the unity of races in ska bands, such as the specials. Third wave is what the genre has developed today. It is harder than traditional or two tone, known for being associated with punk.
