Ska punk is a fusion music genre that combines ska and punk rock. It achieved its highest level of commercial success in the United States in the late 1990s.Ska-core (sometimes spelled skacore) is a subgenre of ska punk, blending ska with hardcore punk.

The characteristics of ska punk vary, due to the fusion of contrasting genres. The more punk-influenced style often features faster tempos, guitar distortion, onbeat punk rock-style interludes (usually the chorus), and punk-style vocals. The more ska-influenced style of ska punk features a more developed instrumentation and a cleaner vocal and musical sound. The common instrumentation includes electric guitar, bass guitar, drums, brass instruments (such as trombones or trumpets), saxophones, and sometimes an organ.

Ska and punk rock were first combined during the 2 Tone movement of the late 1970s, by bands such as The Specials, The Selecter, The Beat, and Madness. The fusion of the two genres became most prevalent in the 1980s, during the third wave of ska, and this is what most people associate with ska punk.

Ska ( /ˈskɑː/, Jamaican [skjæ]) is a music genre that originated in Jamaica in the late 1950s, and was the precursor to rocksteady and reggae. Ska combined elements of Caribbean mento and calypso with American jazz and rhythm and blues. It is characterized by a walking bass line accented with rhythms on the upbeat. In the early 1960s, ska was the dominant music genre of Jamaica and was popular with British mods. Later it became popular with many skinheads.

Music historians typically divide the history of ska into three periods: the original Jamaican scene of the 1960s (First Wave), the English 2 Tone ska revival of the late 1970s (Second Wave) and the third wave ska movement, which started in the 1980s (Third Wave) and rose to popularity in the US in the 1990s.

There are different theories about the origins of the word ska. Ernest Ranglin claimed that the term was coined by musicians to refer to the "skat! skat! skat!" scratching guitar strum. Another explanation is that at a recording session in 1959 produced by Coxsone Dodd, double bassist Cluett Johnson instructed guitarist Ranglin to "play like ska, ska, ska", although Ranglin has denied this, stating "Clue couldn't tell me what to play!" A further theory is that it derives from Johnson's word skavoovie, with which he was known to greet his friends.Jackie Mittoo insisted that the musicians themselves called the rhythm Staya Staya, and that it was Byron Lee who introduced the term 'ska'.

Punk or punks may refer to:

Ernesto "Che" Guevara (Spanish pronunciation: [ˈtʃe ɣeˈβaɾa]; June 14, 1928 – October 9, 1967), commonly known as el Che or simply Che, was an Argentine Marxist revolutionary, physician, author, intellectual, guerrilla leader, diplomat, and military theorist. A major figure of the Cuban Revolution, his stylized visage has become a ubiquitous countercultural symbol of rebellion and global insignia within popular culture.

As a young medical student, Guevara traveled throughout Latin America and was radically transformed by the endemic poverty and alienation he witnessed. His experiences and observations during these trips led him to conclude that the region's ingrained economic inequalities were an intrinsic result of capitalism, monopolism, neocolonialism, and imperialism, with the only remedy being world revolution. This belief prompted his involvement in Guatemala's social reforms under President Jacobo Arbenz, whose eventual CIA-assisted overthrow solidified Guevara's political ideology. Later, while living in Mexico City, he met Raúl and Fidel Castro, joined their 26th of July Movement, and sailed to Cuba aboard the yacht, Granma, with the intention of overthrowing U.S.-backed Cuban dictator Fulgencio Batista. Guevara soon rose to prominence among the insurgents, was promoted to second-in-command, and played a pivotal role in the victorious two-year guerrilla campaign that deposed the Batista regime.
