Question:
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.

input: In 2006, Colter returned to recording with a new studio album released on the Shout! Factory label, Out of the Ashes. "Out of the Ashes" was Colter's first studio album in over 20 years. The album was produced by Don Was and reflected on Jennings' death. Jennings had an unused vocal, "Out of the Rain," which was featured on the track. The album was given many positive reviews, including Allmusic, which gave the album four out of five stars in 2006. Out of the Ashes was her first album since 1981 to chart on the Top Country Albums chart, peaking at No. 61. In 2007 Colter recorded a duet version of her 1975 hit "I'm Not Lisa" with Deana Carter on her 2007 album, The Chain. In 2017, Colter and Jan Howard provided guest vocals to a track appearing on Written In Song, an album by Jeannie Seely. The song, called "We're Still Hangin' In There Ain't We Jessi", references how Seely and Colter are seemingly two of the only women in country music who managed to have a successful marriage. Colter's first album in eleven years, The Psalms was released on March 24 via Legacy Recordings. The album consisted of Colter's favourite Book of Psalms passages put to music and was produced by Lenny Kaye, who recalled an evening when he, Colter, Jennings and Patti Smith were having dinner together in 1995 when Colter began to sing passages of the Bible. Kaye stated that he was "transfixed" and kept the evening in his mind until he convinced Colter to record those renditions in 2007, with the album being recorded over the course of two sessions, along with a further two in 2008. Of the album, Kate stated that "we tried to choose songs that weren't about warring peoples but more about comfort and reconciliation". On April 11, 2017, Colter released a tell-all memoir titled "An Outlaw and a Lady: A Memoir of Music, Life with Waylon, and the Faith That Brought Me Home".

Answer the question at the end by quoting:

Chapter 27 is a 2007 biographical drama film depicting the murder of John Lennon by Mark David Chapman. It was written and directed by Jarrett Schaefer, based on the book Let Me Take You Down by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman. The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Its title is a reference to J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and suggests a continuation of the book.
The script took Schaefer four years to write, but when it was finished, the film came together quickly. With the help of producers Alexandra Milchan and Robert Salerno, Schaefer cast Jared Leto as Mark David Chapman. For his role, Leto gained 67 pounds (30 kg) by drinking microwaved pints of ice cream mixed with soy sauce and olive oil every night. Gaining the weight, he said, was tougher than dieting himself into skeletal shape for his role as drug addict Harry Goldfarb in Requiem for a Dream (2000). The abruptness of Leto's weight gain gave him gout. He had to use a wheelchair due to the stress of the sudden increase in weight put on his body. After the shooting of the film, Leto quickly went on a liquid diet. He explained, "I've been fasting ever since. I've been doing this very strange, like, lemon and cayenne pepper and water fast. I didn't eat any food for 10 days straight; I think I lost 20 pounds that first 10 days." Losing the excess weight after Chapter 27 proved a challenge. "It took about a year to get back to a place that felt semi-normal," he said; "I don't know if I'll ever be back to the place I was physically. I'd never do it again; it definitely gave me some problems." Twenty-two years prior to this film's production, actor Mark Lindsay Chapman, while professionally using the name Mark Lindsay, had been almost cast as John Lennon in the biopic John and Yoko: A Love Story (1985). Yoko Ono had been deeply involved in the production and had herself been initially impressed with his audition and approved his casting prior to discovering his full name was Mark Lindsay Chapman. She then nixed his casting on the grounds it was "bad karma", and a great deal of press attention was given to his having almost gotten the role. The director of Chapter 27, Jarrett Schaefer, auditioned many Lennon impersonators, but was especially impressed with Mark Lindsay Chapman's tape because he conveyed the "tough town" street-smart quality of Lennon that the impersonators failed to convey, as they always played Lennon as larger-than-life. Schaefer described Lennon as having a "chip on his shoulder and always cracking these cynical one-liners", and felt that actor Chapman was best at conveying this quality. Schaefer had some difficulty negotiating the casting with the film's producers because of Chapman's name. After Chapman was cast, he asked Chapman how he should be billed to which Chapman replied "Mark fucking Lindsay Chapman. That's my fucking name." Schaefer remarks that this was so reflective of how Lennon talked, it just reinforced his sense that Chapman was right for the part.
