Answer the question at the end by quoting:

The Olmecs were the earliest known major civilization in Mexico following a progressive development in Soconusco. They lived in the tropical lowlands of south-central Mexico, in the present-day states of Veracruz and Tabasco. It has been speculated that the Olmecs derive in part from neighboring Mokaya or Mixe-Zoque. The Olmecs flourished during Mesoamerica's formative period, dating roughly from as early as 1500 BCE to about 400 BCE. Pre-
Little is directly known about the societal or political structure of Olmec society. Although it is assumed by most researchers that the colossal heads and several other sculptures represent rulers, nothing has been found like the Maya stelae (see drawing) which name specific rulers and provide the dates of their rule.  Instead, archaeologists relied on the data that they had, such as large- and small-scale site surveys. These provided evidence of considerable centralization within the Olmec region, first at San Lorenzo and then at La Venta - no other Olmec sites come close to these in terms of area or in the quantity and quality of architecture and sculpture.  This evidence of geographic and demographic centralization leads archaeologists to propose that Olmec society itself was hierarchical, concentrated first at San Lorenzo and then at La Venta, with an elite that was able to use their control over materials such as water and monumental stone to exert command and legitimize their regime.  Nonetheless, Olmec society is thought to lack many of the institutions of later civilizations, such as a standing army or priestly caste. And there is no evidence that San Lorenzo or La Venta controlled, even during their heyday, all of the Olmec heartland. There is some doubt, for example, that La Venta controlled even Arroyo Sonso, only some 35 km (22 mi) away. Studies of the Tuxtla Mountain settlements, some 60 km (37 mi) away, indicate that this area was composed of more or less egalitarian communities outside the control of lowland centers.

What are their political orientation?

an elite that was able to use their control over materials such as water and monumental stone to exert command and legitimize their regime.

Some context: John Townes Van Zandt (March 7, 1944 - January 1, 1997), better known as Townes Van Zandt, was an American singer-songwriter. He is widely held in high regard for his poetic, often heroically sad songs. In 1983, six years after Emmylou Harris had first popularized it, Willie Nelson and Merle Haggard covered his song "Pancho and Lefty", reaching number one on the Billboard country music chart. Much of his life was spent touring various dive bars, often living in cheap motel rooms and backwoods cabins.
Van Zandt married Fran Petters on August 26, 1965; a son, John Townes "J.T." Van Zandt II, was born to them on April 11, 1969, in Houston. The couple divorced on January 16, 1970. She would later remarry, changing her last name to Lohr. He began dating Cindy Morgan in 1974 and married her in 1978. Townes and Cindy became estranged for much of the early 1980s, and were divorced on February 10, 1983, in Travis County, Texas. They had no children together.  Van Zandt's third and final marriage was to Jeanene Munsell (born February 21, 1957). They met on December 9, 1980 at a memorial for John Lennon. When the terminally-ill Dorothy Van Zandt learned that her son had impregnated Munsell, she told him, "You're going to do the right thing and honor that baby." He soon divorced his estranged second wife and married Munsell on March 14, 1983; their first child, William Vincent, was born ten days later. Another child, Katie Belle, was born February 14, 1992. Van Zandt and Munsell were divorced on May 2, 1994. However, the two remained close until Townes' death, and Jeanene was an executrix of his estate.  Around the time of their April 1993 separation, Jeanene coaxed the musician into signing over the publishing rights of his entire back catalog and recording royalties to her and their children. Townes's only source of income after this point was money received from concert engagements, and even then, Townes would frequently visit his ex-wife and "give her all the money in his pockets." Following their divorce in 1994, his only worldly possessions were listed as a 1989 GMC Truck with camper shell, a 1984 Honda Shadow motorcycle and a 1983 Starwind 22-foot boat named Dorothy; he also retained sole ownership of his family inheritance of "ownership in oil lease and mineral rights."  At the time of his death, he had begun a long-distance relationship with a woman named Claudia Winterer from Darmstadt, Germany. The two met in November 1995 during a concert of his in Hanau, Germany. Van Zandt told several friends that he planned on marrying Winterer, but the two never became formally engaged.
How did his other marriages end?
A: Van Zandt and Munsell were divorced on May 2, 1994. However, the two remained close until Townes' death, and Jeanene was an executrix of his estate.

IN: Nicholas Edward Cave  (born 22 September 1957) is an Australian musician, singer-songwriter, author, screenwriter, composer and occasional film actor, best known as the frontman of the rock band Nick Cave and the Bad Seeds. Cave's music is generally characterised by emotional intensity, a wide variety of influences, and lyrical obsessions with death, religion, love and violence. Born and raised in rural Victoria, Cave studied art before turning to music in the 1970s. As frontman of the Boys Next Door (later renamed the Birthday Party), he became a central figure in Melbourne's burgeoning post-punk scene.

Cave released his first book, King Ink, in 1988. It is a collection of lyrics and plays, including collaborations with Lydia Lunch. In 1997, he followed up with King Ink II, containing lyrics, poems, and the transcript of a radio essay he did for the BBC in July 1996, "The Flesh Made Word," discussing in biographical format his relationship with Christianity.  While he was based in West Berlin, Cave started working on what was to become his debut novel, And the Ass Saw the Angel (1989). Significant crossover is evident between the themes in the book and the lyrics Cave wrote in the late stages of the Birthday Party and the early stage of his solo career. "Swampland", from Mutiny, in particular, uses the same linguistic stylings ('mah' for 'my', for instance) and some of the same themes (the narrator being haunted by the memory of a girl called Lucy, being hunted like an animal, approaching death and execution). On 21 January 2008, a special edition of Cave's novel And the Ass Saw the Angel was released. Cave's second novel The Death of Bunny Munro was published on 8 September 2009 by Harper Collins books. Telling the story of a sex-addicted salesman, it was also released as a binaural audio-book produced by British Artists Iain Forsyth and Jane Pollard and an iPhone app. The book originally started as a screenplay Cave was going to write for John Hillcoat.  Aside from movie soundtracks, Cave also wrote the screenplays for Hillcoat's The Proposition in 2005, and Lawless (based on the novel by Matt Bondurant) in 2011.  As proof of his interest in scripture, so evident in his lyrics and his prose writing, Cave wrote the foreword to a Canongate publication of the Gospel according to Mark, published in the UK in 1998. The American edition of the same book (published by Grove Press) contains a foreword by the noted American writer Barry Hannah.  Cave is a contributor to a 2009 rock biography of the Triffids, Vagabond Holes: David McComb and the Triffids, edited by Australian academics Niall Lucy and Chris Coughran.

Did he write for any movies or film?
