Oppression is the exercise of authority or power in a burdensome, cruel, or unjust manner. It can also be defined as an act or instance of oppressing, the state of being oppressed, and the feeling of being heavily burdened, mentally or physically, by troubles, adverse conditions, and anxiety.

The systematic; socially supported mistreatment and exploitation of a group or category of people by anyone.

"Institutional Oppression occurs when established laws, customs, and practices systematically reflect and produce inequities based on one’s membership in targeted social identity groups. If oppressive consequences accrue to institutional laws, customs, or practices, the institution is oppressive whether or not the individuals maintaining those practices have oppressive intentions."

Anarchists and other libertarian socialists argue that police and law themselves are oppression. The term oppression in such instances to refer to the subordination of a given group or social category by unjust use of force, authority, or societal norms in order to achieve the effects noted above. When institutionalized, formally or informally, it may achieve the dimension of systematic oppression. Oppression is customarily experienced as a consequence of, and expressed in, the form of a prevailing, if unconscious, assumption that the given target is in some way inferior. Oppression is rarely limited solely to formal government action: an individual may be the particular focus of oppression or persecution and in such circumstances have no group membership in which to share, and thus maybe mitigate, the burden of ostracism.

Benjamin Chase "Ben" Harper (born October 28, 1969) is an American singer-songwriter and musician. Harper plays an eclectic mix of blues, folk, soul, reggae and rock music and is known for his guitar-playing skills, vocals, live performances and activism. Harper's fan base spans several continents. His albums have been commercially successful in North America, Europe and Oceania. Harper is a two-time Grammy Award winner as well, winning awards for Best Pop Instrumental Performance and Best Traditional Soul Gospel Album, in 2005.

Harper was born in Claremont, in California's Inland Empire. His father, Leonard, was of African-American and Cherokee ancestry, and his mother, Ellen Chase-Verdries, is Jewish. His maternal great-grandmother was a Russian-Lithuanian Jew. His parents divorced when he was age five, and he grew up with his mother's family. Harper has two brothers, Joel and Peter.

Harper began playing guitar as a child. His maternal grandparents' music store The Folk Music Center and Museum laid a foundation of folk and blues for the artist, complemented by regular patrons Leonard Cohen, Taj Mahal and David Lindley and quotes of William Shakespeare and Robert Frost made often by his grandfather. At the age of 12, Harper played his first gig. During the '80s, in his teen years, Harper began to play the slide guitar, mimicking the style of Robert Johnson. Next, Harper refined his style, taking up the Weissenborn slide guitar. Harper broke out of the Inland Empire after being offered an invitation by Taj Mahal to tour with the artist. They recorded Taj Mahal's album Follow the Drinking Gourd, released in November 1990, and toured Hawaii.

Léo Ferré (24 August 1916 – 14 July 1993) was a Franco-Monegasque poet, composer, singer and musician.

Born in Monaco, Ferré mixed love and melancholy with moral anarchy, lyricism with slang, rhyming verse with prose monologues. He moved from music-hall to orchestral music, breaking free from the traditional song structure during the 1970s, inventing his own musical territory, powerfully dramatic and unique. He also set to music several poems by the French poètes maudits, such as François Villon, Charles Baudelaire, Paul Verlaine, and Arthur Rimbaud, as well as French poets from the 20th century like Guillaume Apollinaire and Louis Aragon.

He took a central place in the French song world and is a prominent figure in this domain. He was involved in anarchism and worked with Radio Libertaire, an anarchist free radio broadcasting in Paris and around France. Along with Georges Brassens and Jacques Brel, he is considered one of the greatest composers and writers of French songs.

Excludes numerous compilations.
