Question: Which documentary came out first, American Pimp or Go Further?
Context: UGK (short for Underground Kingz) was an American hip hop duo from Port Arthur, Texas, formed in 1987, by Chad "Pimp C" Butler and Bernard "Bun B" Freeman.  They released their first major-label album "Too Hard to Swallow", in 1992, followed by several other albums charting on the "Billboard" 200 and Top R&B/Hip-Hop Albums charts, including the self-titled "Underground Kingz" album, which debuted at number one on the "Billboard" 200, in August 2007.  The duo has also been featured on hit singles by several other artists, such as on "Big Pimpin'" by Jay-Z and "Sippin' on Some Syrup" by Three 6 Mafia.  Pimp C founded UGK Records in late 2005.  On December 4, 2007, Pimp C was found dead in a West Hollywood, California hotel room. "'What Up?'"  is a posthumous single by American rapper Pimp C, featuring rapper Drake and former-fellow UGK member Bun B.  It's the lead single from Pimp C's first posthumous studio album, and third studio album over all, The Naked Soul of Sweet Jones. A Place to Bury Strangers is the first album from the shoegazing band A Place to Bury Strangers.  Most of the songs were recorded between 2004 and 2006 and were released as series of "ad hoc" EPs which were sold at shows by the band.  The band came to the attention of Killer Pimp owner Jon Whitney in late 2006 and he asked if he could have the songs remastered and release them as an album on CD.  The band deliberated over whether this would be a good move for some time before finally agreeing.  The album was released in a limited edition in August 2007.  This soon sold out and several repressings were made.  As of March 2008 further pressings are ongoing.  The album was also released on vinyl by Important Records as a limited edition of 1,000 copies with 300 on clear vinyl and 700 on black.  These sold out and a second edition of 1,000 with 300 on red/white splatter was pressed.  A third pressing of 1,000 was made with the first 300 on white in July 2008. Robert Beck (born Robert Lee Maupin or Robert Moppins, Jr.; August 4, 1918 – April 28, 1992), better known as Iceberg Slim, was an American pimp who subsequently became an influential author among a primarily African-American readership.  Beck's novels were adapted into movies, and the imagery and tone of Beck's fiction have been acknowledged as an influence by several rap musicians, including Ice T and Ice Cube, whose names are homages to Beck. Stanley Kubrick's Boxes is a 2008 documentary film directed by Jon Ronson about the film director Stanley Kubrick.  Ronson's intent was not to create a biography of the filmmaker but rather to understand Kubrick by studying the director's vast personal collection of memorabilia related to his feature films.  The documentary came about in 1998 when Ronson received a request from Kubrick's estate for a copy of a documentary Ronson made about the Holocaust (Ronson was unaware that it was Kubrick who was asking for the film until months later).  A year later, as Ronson was making plans to conduct a rare interview with the director, Kubrick suddenly died after completing work on his final film "Eyes Wide Shut".  To his surprise, Ronson was invited to Kubrick's house by his widow.  When he arrived, he found that half the house was filled by more than one thousand boxes containing snap shots, newspaper clippings, film out-takes, notes, and fan letters which the director used for research towards each of his films. American Pimp is a 1999 documentary that examines the pimp subculture in the United States.  It was directed by the Hughes Brothers, the filmmakers behind "Menace II Society" and "Dead Presidents". Ellis Albert "Al" Swearengen (July 8, 1845 – November 15, 1904) was an American pimp and entertainment entrepreneur who ran the Gem Theater, a notorious brothel, in Deadwood, South Dakota for 22 years during the late 19th century. Go Further is a 2003 documentary film by Ron Mann starring Woody Harrelson and a group of other environmental activists riding around in a large, bio-fueled bus.  The tour was called the Simple Organic Living Tour and it was produced by cause-related marketers the Spitfire Agency.  The film debuted at the South by Southwest Film Festival in March 2003, and at the Toronto International Film Festival in September 2003, where it was first runner-up for the People's Choice Award.  It was also nominated for a Genie Award for Best Documentary.  The film features cameos by Dave Matthews, Natalie Merchant, Ken Kesey, Bob Weir (of the Grateful Dead), Michael Franti (of Spearhead), Anthony Kiedis (of Red Hot Chili Peppers), Rob Heydon, Medeski Martin & Wood, and The String Cheese Incident. The actuality film is a non-fiction film genre that, like the documentary film, uses footage of real events, places, and things, yet unlike the documentary is not structured into a larger argument, picture of the phenomenon or coherent whole.  In practice, actuality films preceded the emergence of the documentary.  During the era of early cinema, actualities—usually lasting no more than a minute or two and usually assembled together into a program by an exhibitor—were just as popular and prominent as their fictional counterparts.  The line between "fact" and "fiction" was not so sharply drawn in early cinema as it would become after the documentary came to serve as the predominant non-fiction filmmaking form.  An actuality film is not like a newspaper article so much as it is like the still photograph that is published along with the article, with the major difference being that it moves.  Apart from the traveling actuality genre, actuality is one film genre that remains strongly related to still photography.
