Some context: Rosa Luxemburg  (also Rozalia Luxenburg; Polish: Roza Luksemburg; 5 March 1871 - 15 January 1919) was a Polish Marxist theorist, philosopher, economist, anti-war activist, and revolutionary socialist who became a naturalized German citizen at the age of 28. She was, successively, a member of the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), the Social Democratic Party of Germany (SPD), the Independent Social Democratic Party (USPD), and the Communist Party of Germany (KPD). In 1915, after the SPD supported German involvement in World War I, she and Karl Liebknecht co-founded the anti-war Spartacus League (Spartakusbund), which eventually became the KPD. During the November Revolution she co-founded the newspaper Die Rote Fahne ("The Red Flag"), the central organ of the Spartacist movement.
Luxemburg wanted to move to Germany to be at the centre of the party struggle, but she had no way of obtaining permission to remain there indefinitely. In April 1897 she married the son of an old friend, Gustav Lubeck, in order to gain a German citizenship. They never lived together and they formally divorced five years later. She returned briefly to Paris, then moved permanently to Berlin to begin her fight for Eduard Bernstein's constitutional reform movement. Luxemburg hated the stifling conservatism of Berlin. She despised Prussian men and resented what she saw as the grip of urban capitalism on social democracy. In the Social Democratic Party of Germany's women's section she met Clara Zetkin, of whom she made a lifelong friend. Between 1907 and his conscription in 1915 she was involved in a love affair with Clara's younger son, Kostja Zetkin, to which approximately 600 surviving letters (now mostly published) bear testimony. Luxemburg was a member of the uncompromising left-wing of the SPD. Their clear position was that the objectives of liberation for the industrial working class and all minorities could be achieved by revolution only.  The recently published Letters of Rosa Luxemburg shed important light on her life in Germany. As Irene Gammel writes in a review of the English translation of the book in The Globe and Mail: "The three decades covered by the 230 letters in this collection provide the context for her major contributions as a political activist, socialist theorist and writer." Her reputation was tarnished by Joseph Stalin's cynicism in Questions Concerning the History of Bolshevism. In his rewriting of Russian events he placed the blame for the theory of permanent revolution on Luxemburg's shoulders, with faint praise for her attacks on Karl Kautsky, which she commenced in 1910.  According to Gammel, "In her controversial tome of 1913, The Accumulation of Capital, as well as through her work as a co-founder of the radical Spartacus League, Luxemburg helped to shape Germany's young democracy by advancing an international, rather than a nationalist, outlook. This farsightedness partly explains her remarkable popularity as a socialist icon and its continued resonance in movies, novels and memorials dedicated to her life and oeuvre." Gammel also notes that for Luxemburg, "the revolution was a way of life," and yet that the letters also challenge the stereotype of "Red Rosa" as a ruthless fighter. But The Accumulation of Capital sparked angry accusations from the Communist Party of Germany; in 1923 Ruth Fischer and Arkadi Maslow denounced the work as "errors", a derivative work of economic miscalculation known as "spontaneity".

Some context: Alecia Beth Moore (born September 8, 1979), known professionally as Pink (often stylized as P!nk), is an American singer, songwriter, dancer and actress. She was signed to her first record label with original R&B girl group, Choice, in 1995. The label, LaFace Records, saw great potential in Pink, offering her a solo deal. Choice disbanded in 1998.
Pink has been credited for breaking boundaries and pushing the envelope throughout her career. She is regarded as the "most trailblazing artist" of her pop generation. Robert Hilburn of the Los Angeles Times says, "Pink stood up for her music, broke the music industry's mold and scored a breakout hit, challenging a school of teen singers to find their own sounds as well." He adds, "[Pink] also started a race among other teen pop stars like Christina Aguilera to add substance to their own sound." Ann Powers refers to her as a "powerhouse vocalist", stating her mix of rebellion, emotional rawness, humor, and "infectious" dance beats created "a model for the mashup approach of latter-day divas such as Katy Perry, Kesha, and even Rihanna." Rob Sheffield of Rolling Stone commented: "I think people respond to her sense of independence and dedication. It inspires people... This is a prolific pop artist who is sometimes famous and successful, sometimes obscure, who nonetheless keeps making her own kind of music."  James Montgomery of MTV describes her as "a fabulously fearless pop artist" who can "out-sing almost anyone out there. She can out-crazy Gaga or Lily. She's the total pop-star package, everything you'd want in a singer/entertainer/icon. And still, she remains oddly off the radar. Such is the price of busting borders". Entertainment Weekly said: "She essentially invented the whole modern wave of Pop Diva Domination: You can draw a straight line from "Get This Party Started" to Katy Perry, Kesha, pre-messianic Lady Gaga, and post-weird Rihanna." Glamour Magazine wrote: "When Pennsylvania-born Alecia Moore debuted in 2000, pop was dominated by long-locked blonds like Britney Spears, Christina Aguilera and Jessica Simpson. Pink changed the game. Without her, the last 13-years of big-voiced, tough chick music is hard to imagine."  Following her performance at the American Music Awards of 2012, LZ Granderson of CNN wrote: "... our culture's biggest sin may well be the auto-tuned syrup we've allowed to dominate the pop charts. All-time chart records are handed to vacuous acts such as the Black Eyed Peas and singing awards are given to vocal lightweights such as Taylor Swift [...] But thank God for Pink. [...] While Christina Aguilera has a tendency to oversing, Britney Spears can't sing, and Lauryn Hill sorta stopped singing, Pink has managed to carve a brilliant 13-year-career by being something that is incredibly rare these days--an artist." British soul singer Adele considers Pink's performance at Brixton Academy in London as one of "the most defining moments" in her life, saying "It was the Missundaztood record, so I was about 13 or 14. I had never heard, being in the room, someone sing like that live. I remember sort of feeling like I was in a wind tunnel, her voice just hitting me. It was incredible."  Pink's work has inspired several other artists including Demi Lovato, Kelly Clarkson, Taylor Swift, Katy Perry, Tegan and Sara, Ashley Tisdale, Alessia Cara, Victoria Justice, Adele, Julia Michaels, and Dua Lipa.
