<P> Byron Lee & the Dragonaires performed ska with Prince Buster, Eric "Monty" Morris, and Jimmy Cliff at the 1964 New York World's Fair . As music changed in the United States, so did ska . In 1965 and 1966, when American soul music became slower and smoother, ska changed its sound accordingly and evolved into rocksteady . However, rocksteady's heyday was brief, peaking in 1967 . By 1968, ska evolved again into reggae . </P> <P> The 2 Tone genre, which began in the late 1970s in the Coventry, England area, was a fusion of Jamaican ska rhythms and melodies with punk rock's more aggressive guitar chords and lyrics . Compared to 1960s ska, 2 Tone music had faster tempos, fuller instrumentation, and a harder edge . The genre was named after 2 Tone Records, a record label founded by Jerry Dammers of The Specials . In many cases, the reworking of classic ska songs turned the originals into hits again in the United Kingdom . </P> <P> The 2 Tone movement promoted racial unity at a time when racial tensions were high in the UK . There were many Specials songs that raised awareness of the issues of racism, fighting and friendship issues . Riots in British cities were a feature during the summer that The Specials song "Ghost Town" was a hit, although this work was in a slower, reggae beat . Most of the 2 Tone bands had multiracial lineups, such as The Beat (known as The English Beat in North America and the British Beat in Australia), The Specials, and The Selecter . Although only on the 2 Tone label for one single, Madness was one of the most effective bands at bringing the 2 Tone genre into the mainstream . The music of this era resonated with white working class youth and West Indian immigrants who experienced the struggles addressed in the lyrics . </P> <P> Third wave ska originated in the punk scene in the late 1980s and became commercially successful in the 1990s . Although some third wave ska has a traditional 1960s sound, most third wave ska is characterized by dominating guitar riffs and large horn sections . Examples of third wave ska bands include The Toasters, Fishbone, The Mighty Mighty Bosstones, Hepcat, The Slackers, Suicide Machines, Voodoo Glow Skulls, Streetlight Manifesto, Reel Big Fish, Less Than Jake, Mad Caddies, The Aquabats, Mustard Plug, The Supertones, Five Iron Frenzy, Buck - o - Nine, Suburban Legends, The Pietasters and Goldfinger . </P>
