Question: When did the person who writes and creates most of her own music drop out of college?

full_context: Document 1: Madonna (entertainer): Besides singing Madonna has the ability to play several musical instruments. She learned to play drum and guitar from her then-boyfriend Dan Gilroy in the late 1970s before joining the Breakfast Club line-up as the drummer. This helped her to form the band Emmy, where she performed as the guitarist and lead vocalist. Madonna later played guitar on her demo recordings. On the liner notes of Pre-Madonna, Stephen Bray wrote: "I've always thought she passed up a brilliant career as a rhythm guitarist." After her career breakthrough, Madonna focused mainly in singing but was also credited for playing cowbell on Madonna (1983) and synthesizer on Like a Prayer (1989). In 1999, Madonna had studied for three months to play the violin for the role as a violin teacher in the film Music of the Heart, before eventually leaving the project. After two decades, Madonna decided to perform with guitar again during the promotion of Music (2000). She took further lessons from guitarist Monte Pittman to improve her guitar skill. Since then Madonna has played guitar on every tour, as well as her studio albums. At the 2002 Orville H. Gibson Guitar Awards, she received nomination for Les Paul Horizon Award, which honors the most promising up-and-coming guitarist.
Document 2: Madonna (entertainer): Madonna's music has been the subject of much analysis and scrutiny. Robert M. Grant, author of Contemporary Strategy Analysis (2005), commented that what has brought Madonna success is "certainly not outstanding natural talent. As a vocalist, musician, dancer, songwriter, or actress, Madonna's talents seem modest." He asserts Madonna's success is in relying on the talents of others, and that her personal relationships have served as cornerstones to the numerous reinventions in the longevity of her career. Madonna's approach was far from the music industry wisdom of "Find a winning formula and stick to it." Her musical career has been a continuous experimentation with new musical ideas and new images and a constant quest for new heights of fame and acclaim. Grant concluded that "having established herself as the queen of popular music, Madonna did not stop there, but continued re-inventing." Musicologist Susan McClary wrote that "Madonna's art itself repeatedly deconstructs the traditional notion of the unified subject with finite ego boundaries. Her pieces explore various ways of constituting identities that refuse stability, that remain fluid, that resist definition."
Document 3: Madonna (entertainer): In The Madonna Companion biographers Allen Metz and Carol Benson noted that more than any other recent pop artist, Madonna had used MTV and music videos to establish her popularity and enhance her recorded work. According to them, many of her songs have the imagery of the music video in strong context, while referring to the music. Cultural critic Mark C. Taylor in his book Nots (1993) felt that the postmodern art form par excellence is video and the reigning "queen of video" is Madonna. He further asserted that "the most remarkable creation of MTV is Madonna. The responses to Madonna's excessively provocative videos have been predictably contradictory." The media and public reaction towards her most-discussed songs such as "Papa Don't Preach", "Like a Prayer", or "Justify My Love" had to do with the music videos created to promote the songs and their impact, rather than the songs themselves. Morton felt that "artistically, Madonna's songwriting is often overshadowed by her striking pop videos."
Document 4: Madonna (entertainer): In 1978, she dropped out of college and relocated to New York City. She had little money and worked as a waitress at Dunkin' Donuts and with modern dance troupes, taking classes at the Alvin Ailey American Dance Theater and eventually performing with Pear Lang Dance Theater. Madonna said of her move to New York, "It was the first time I'd ever taken a plane, the first time I'd ever gotten a taxi cab. I came here with $35 in my pocket. It was the bravest thing I'd ever done." She started to work as a backup dancer for other established artists. Madonna claimed that during a late night she was returning from a rehearsal, when a pair of men held her at knifepoint and forced her to perform fellatio. Madonna later commented that "the episode was a taste of my weakness, it showed me that I still could not save myself in spite of all the strong-girl show. I could never forget it."
Document 5: Madonna (entertainer): Possessing a mezzo-soprano vocal range, Madonna has always been self-conscious about her voice, especially in comparison to her vocal idols such as Ella Fitzgerald, Prince, and Chaka Khan. Mark Bego, author of Madonna: Blonde Ambition, called her "the perfect vocalist for lighter-than-air songs", despite not being a "heavyweight talent." According to MSNBC critic Tony Sclafani, "Madonna's vocals are the key to her rock roots. Pop vocalists usually sing songs "straight," but Madonna employs subtext, irony, aggression and all sorts of vocal idiosyncrasies in the ways John Lennon and Bob Dylan did." Madonna used a bright, girlish vocal timbre in her early albums which became passé in her later works. The change was deliberate since she was constantly reminded of how the critics had once labelled her as "Minnie Mouse on helium". During the filming of Evita, Madonna had to take vocal lessons, which increased her range further. Of this experience she commented, "I studied with a vocal coach for Evita and I realized there was a whole piece of my voice I wasn't using. Before, I just believed I had a really limited range and was going to make the most of it."
Document 6: Madonna (entertainer): Before emerging as a pop star, Madonna has spent her early years in rock music alongside her bands, Breakfast Club and Emmy. While performing with Emmy, Madonna recorded about 12-14 songs which resemble the punk rock of that period. Her early rock roots also can be found on the demo album Pre-Madonna. Stephen Thomas Erlewine noted that with her self-titled debut album, Madonna began her career as a disco diva, in an era that did not have any such divas to speak of. In the beginning of the '80's, disco was an anathema to the mainstream pop, and according to Erlewine, Madonna had a huge role in popularizing dance music as mainstream music. The album's songs reveal several key trends that have continued to define her success, including a strong dance-based idiom, catchy hooks, highly polished arrangements and Madonna's own vocal style. Her second album, Like a Virgin (1984), foreshadowed several trends in her later works. It contained references to classical works (pizzicato synthesizer line that opens "Angel"); potential negative reaction from social groups ("Dress You Up" was blacklisted by the Parents Music Resource Center); and retro styles ("Shoo-Bee-Doo", Madonna's homage to Motown).
Document 7: Madonna (entertainer): Madonna has received acclaim as a role model for businesswomen in her industry, "achieving the kind of financial control that women had long fought for within the industry", and generating over $1.2 billion in sales within the first decade of her career. Professor Colin Barrow from Cranfield School of Management described Madonna as "America's smartest businesswoman ... who has moved to the top of her industry and stayed there by constantly reinventing herself." London Business School academics called her a "dynamic entrepreneur" worth copying; they identified her vision of success, her understanding of the music industry, her ability to recognize her own performance limits (and thus bring in help), her willingness to work hard and her ability to adapt as the keys to her commercial success. Morton wrote that "Madonna is opportunistic, manipulative, and ruthless—somebody who won't stop until she gets what she wants—and that's something you can get at the expense of maybe losing your close ones. But that hardly mattered to her." Hazel Blackmore and Rafael Fernández de Castro in the book ¿Qué es Estados Unidos? from the Fondo de Cultura Económica, noted: "Madonna has been undoubtedly the most important woman in the history of popular music and a great businesswoman in herself; creating fashion, breaking taboos and provoking controversies."
Document 8: Madonna (entertainer): Madonna is dedicated to Kabbalah, and in 2004 she adopted the name Esther which in Persian means "star". She has donated millions of dollars to New York and London schools teaching the subject. She faced opposition from rabbis who felt Madonna's adoption of the Kabbalah was sacrilegious and a case of celebrity dilettantism. Madonna defended her studies, saying: "It would be less controversial if I joined the Nazi Party", and that her involvement with the Kabbalah is "not hurting anybody". The influence of the Kabbalah was subsequently observed in Madonna's music, especially albums like Ray of Light and Music. During the Re-Invention World Tour, at one point in the show, Madonna and her dancers wore T-shirts that read "Kabbalists Do It Better". Her 2012 MDNA album has also drawn many influences from her Catholic upbringing, and since 2011 she has been attending meetings and services at an Opus Dei center, a Catholic institution that encourages spirituality through every day life.
Document 9: Madonna (entertainer): Madonna Louise Ciccone (/tʃɪˈkoʊni/; Italian: [tʃikˈkoːne]; born August 16, 1958) is an American singer, songwriter, actress, and businesswoman. She achieved popularity by pushing the boundaries of lyrical content in mainstream popular music and imagery in her music videos, which became a fixture on MTV. Madonna is known for reinventing both her music and image, and for maintaining her autonomy within the recording industry. Music critics have acclaimed her musical productions, which have generated some controversy. Often referred to as the "Queen of Pop", she is often cited as an influence by other artists.
Document 10: Madonna (entertainer): In 1985, Madonna commented that the first song to ever make a strong impression on her was "These Boots Are Made for Walkin'" by Nancy Sinatra; she said it summed up her own "take-charge attitude". As a young woman, she attempted to broaden her taste in literature, art, and music, and during this time became interested in classical music. She noted that her favorite style was baroque, and loved Mozart and Chopin because she liked their "feminine quality". Madonna's major influences include Karen Carpenter, The Supremes and Led Zeppelin, as well as dancers Martha Graham and Rudolf Nureyev. She also grew up listening to David Bowie, whose show was the first rock concert she ever attended.
Document 11: Madonna (entertainer): Madonna entered mainstream films in February 1985, beginning with a brief appearance as a club singer in Vision Quest, a romantic drama film. Its soundtrack contained two new singles, her U.S. number-one single, "Crazy for You", and another track "Gambler". She also played the title role in the 1985 comedy Desperately Seeking Susan, a film which introduced the song "Into the Groove", her first number-one single in the UK. Her popularity relegated the film as a Madonna vehicle, despite not having lead actress billing. The New York Times film critic Vincent Canby named it one of the ten best films of 1985.Beginning in April 1985, Madonna embarked on her first concert tour in North America, The Virgin Tour, with the Beastie Boys as her opening act. She progressed from playing CBGB and the Mudd Club to playing large sporting arenas. The tour saw the peak of Madonna wannabe phenomenon, with lots of female attendees dressing like her. At that time, she released two more hits, "Angel" and "Dress You Up", making all four singles from the album peak inside the top five on the Hot 100 chart. In July, Penthouse and Playboy magazines published a number of nude photos of Madonna, taken in New York in 1978. She had posed for the photographs as she needed money at the time, and was paid as little as $25 a session. The publication of the photos caused a media uproar, but Madonna remained "unapologetic and defiant". The photographs were ultimately sold for up to $100,000. She referred to these events at the 1985 outdoor Live Aid charity concert, saying that she would not take her jacket off because "[the media] might hold it against me ten years from now."
Document 12: Madonna (entertainer): Born in Bay City, Michigan, Madonna moved to New York City in 1977 to pursue a career in modern dance. After performing in the music groups Breakfast Club and Emmy, she signed with Sire Records (an auxiliary label of Warner Bros. Records) in 1982 and released her self-titled debut album the following year. She followed it with a series of commercially and critcally successful albums, including the Grammy Award winners Ray of Light (1998) and Confessions on a Dance Floor (2005). Throughout her career, Madonna has written and produced most of her songs, with many of them reaching number one on the record charts, including "Like a Virgin", "Into the Groove", "Papa Don't Preach", "Like a Prayer", "Vogue", "Frozen", "Music", "Hung Up", and "4 Minutes".
Document 13: Madonna (entertainer): Madonna turned to her paternal grandmother for solace. The Ciccone siblings resented housekeepers and invariably rebelled against anyone brought into their home ostensibly to take the place of their beloved mother. Madonna later told Vanity Fair that she saw herself in her youth as a "lonely girl who was searching for something. I wasn't rebellious in a certain way. I cared about being good at something. I didn't shave my underarms and I didn't wear make-up like normal girls do. But I studied and I got good grades.... I wanted to be somebody." Terrified that her father Tony could be taken from her as well, Madonna was often unable to sleep unless she was near him.
Document 14: Madonna (entertainer): In September 1993, Madonna embarked on The Girlie Show World Tour, in which she dressed as a whip-cracking dominatrix surrounded by topless dancers. In Puerto Rico she rubbed the island's flag between her legs on stage, resulting in outrage among the audience. In March 1994, she appeared as a guest on the Late Show with David Letterman, using profanity that required censorship on television, and handing Letterman a pair of her panties and asking him to smell it. The releases of her sexually explicit films, albums and book, and the aggressive appearance on Letterman all made critics question Madonna as a sexual renegade. Critics and fans reacted negatively, who commented that "she had gone too far" and that her career was over.
Document 15: Madonna (entertainer): Throughout her career Madonna has been involved in writing and producing most of her own music. Madonna's early songwriting skill was developed during her time with the Breakfast Club in 1979. According to author Carol Gnojewski, her first attempts at songwriting are perceived as an important self-revelation, as Madonna said: "I don't know where [the songs] came from. It was like magic. I'd write a song every day. I said 'Wow, I was meant to do this'." Mark Kamins, her first producer, believed that Madonna is "a much underrated musician and lyricist." Rolling Stone has named her "an exemplary songwriter with a gift for hooks and indelible lyrics." According to Freya Jarman-Ivens, Madonna's talent for developing "incredible" hooks for her songs allows the lyrics to capture the attention of the audience, even without the influence of the music. As an example, Jarman-Ivens cites the 1985 single "Into the Groove" and its line "Live out your fantasy here with me, just let the music set you free; Touch my body, and move in time, now I know you're mine." Madonna's songwriting are often autobiographical over the years, dealing with various themes from love and relationships to self-respect and female empowerment. Her songs also speak about taboo and unconventional issues of their period, such as sexuality and AIDS on Erotica (1992). Many of her lyrics contain innuendos and double entendre, which lead to multiple interpretations among music critics and scholars. Madonna has been nominated for being inducted into the Songwriters Hall of Fame twice, for 2014 and 2016 ceremony. Rolling Stone listed Madonna at number 56 on the "100 Greatest Songwriters of All Time".
