Problem: Celtic Frost () were a Swiss heavy metal band from Zurich. They are known for their strong influence on the development of extreme metal. Formed in 1982 as Hellhammer, the band became Celtic Frost in 1984 and was active until 1993. It re-formed in 2001 and disbanded following frontman Tom Gabriel Fischer's departure in 2008.

One of their more influential recordings was 1985's To Mega Therion which did not feature Ain on bass, but stand-in Dominic Steiner. The cover artwork is a painting by H.R. Giger entitled Satan I. The album was a major influence on the then-developing death metal and black metal genres. Ain did return after the album was recorded however. In 1987 followed Into the Pandemonium. The album is more varied than many of Celtic Frost's past LPs, with unlikely covers (Wall of Voodoo's "Mexican Radio"), emotionally charged love songs, the album's recurring industrial-influenced rhythmic songs of demons and destruction, traditional Frost styled songs about dreams and fear, and a dark, classical piece with female vocals.  The album is vastly different from the band's previous work and cemented its late 80s avant-garde metal term; it is also a departure from the extreme style found on the band's previous albums, Morbid Tales and To Mega Therion that Celtic Frost had become known for. However, it does have the recurring symphonic elements found on previous albums. The album has a more classic heavy metal style within the songs with elements of industrial, classical and gothic rock, and even has an industrial/electronic body music (EBM)-inspired rhythm in "One in Their Pride". It does have a few black metal elements remaining in Warrior's vocals, though, and some thrash-influenced guitar riffs.  These albums were some of the pivotal LPs for underground metal and introduced a new and more varied sound. Celtic Frost, along with Venom and Bathory were pioneers in the still underground black metal scene, although Celtic Frost were much more experimental with the addition of classical instruments, operatic female vocals and sampling. Celtic Frost was often labeled by critics as avant-garde metal.

What was released during the 1985?

Answer with quotes: recordings was 1985's To Mega Therion

Background: Landon was born Eugene Maurice Orowitz on October 31, 1936, in Forest Hills, a neighborhood of Queens, New York. His parents were Peggy (nee O'Neill; a dancer and comedian) and Eli Maurice Orowitz. Eugene was the Orowitz family's second child; their daughter, Evelyn, was born three years earlier. In 1941, when Landon was four years old, he and his family moved to the Philadelphia suburb of Collingswood, New Jersey.
Context: The year after Bonanza was canceled, Landon went on to star as Charles Ingalls in the pilot of what became another very successful television series, Little House on the Prairie, again for NBC. The show was taken from a 1935 book written by Laura Ingalls Wilder, whose character in the show was played by nine-year-old actress Melissa Gilbert. In addition to Gilbert, two other unknown actresses also starred on the show: Melissa Sue Anderson, who appeared as Mary Ingalls, the oldest daughter in the Ingalls family, and Karen Grassle as Charles' wife, Caroline. Landon served as executive producer, writer, and director of Little House. The show, a success in its first season, emphasized family values and relationships. Little House became Landon's second-longest running series.  The show was nominated for several Emmy and Golden Globe awards. After eight seasons, Little House was retooled by NBC in 1982 as Little House: A New Beginning, which focused on the Wilder family and the Walnut Grove community. Though Landon remained the show's executive producer, director and writer, A New Beginning did not feature Charles and Caroline Ingalls. A New Beginning was actually the final chapter of Little House, as the series ended in 1983. The following year, three made-for-television movies aired.  Melissa Gilbert said of her on- and off-screen chemistry with Landon, "He was very much like a 'second father' to me. My own father passed away when I was 11, so, without really officially announcing it, Michael really stepped in." When not working on the Little House set, Gilbert spent most of the weekends visiting Landon's real-life family. She once said, "The house was huge. We ran like banshees through that house, and Mike would hide behind doorways and jump out and scare us." In a 2015 interview, Gilbert said of Landon, "He gave me so much advice...the overall idea that he pounded into me, from a little girl, into my brain was that nothing's more important than 'Home & Family'; no success, no career, no achievements, no accomplishments, nothing's more important than loving the people you love and contributing to a community. Though we were working, really, really hard, we were 'Not Saving The World', one episode of television at a time, we're just entertaining people and there are more important things to do.... and have fun; no matter what."
Question: did he have a close connection with any of the others?
Answer: 

Question:
Paul Verhoeven was born on 18 July 1938, the son of a school teacher, Wim Verhoeven, and a hat maker, Nel van Schaardenburg. Although he was born in Amsterdam, the family lived in the village of Slikkerveer. In 1943 the family moved to The Hague, the location of the German headquarters in the Netherlands during World War II. The Verhoeven house was near a German military base with V1 and V2-rocket launchers, which was repeatedly bombed by allied forces.
After about 20 years of working and living in the United States, Verhoeven returned to the Netherlands for the shooting of a new film. Together with his screenwriter Gerard Soeteman, Verhoeven made Black Book (2006). The director was hailed by the host of the Netherlands Film Festival with the words "The return of a hero." Black Book eventually won six Golden Calves at this festival, including Best Director. When the shooting of Black Book was delayed due to financial issues, there was speculation about a new production. The film Beast of Bataan had been announced, but once the shooting for Black Book resumed, the other film was never realized. Since his return to European cinema in 2006 with Black Book, Verhoeven has been connected to a large number of projects, but for the moment none of them has come to fruition. Some of those titles were produced with other directors at the helm, such as The Paperboy.  Finally, in a rather unexpected twist, Verhoeven followed Black Book by directing a movie in French: Elle, an adaptation of a novel by Philippe Djian. The film by Verhoeven, a psycho-thriller where Isabelle Huppert plays a rape victim, was selected in the Official Competition at the Cannes International Film Festival, where it obtained very favourable reviews.  Verhoeven has been a knight in the Order of the Netherlands Lion since 2007. In December 2016 it was announced that Verhoeven would be the President of the Jury for the 67th Berlin International Film Festival, scheduled to take place in February 2017.  In April 2017 his next French film titled Blessed Virgin was announced, to start filming in August of the same year. It is a biographical film about the life of Benedetta Carlini, which will be portrayed by Elle co-star Virginie Efira, and is an adaptation of the non-fiction book Immodest Acts - The life of a lesbian nun in Renaissance Italy by Judith C. Brown.
