Problem: Background: Autechre () are an English electronic music duo consisting of Rob Brown and Sean Booth, both from Rochdale, Greater Manchester. Formed in 1987, they are one of the most popular acts signed to UK electronic label Warp Records, through which all of Autechre's full-length albums have been released beginning in 1993 with Incunabula. They have also worked closely with the label Skam. The music of Autechre has shifted gradually throughout their career, from their earlier work's roots in techno, electro, and hip hop to later albums often considered experimental in nature, featuring complex drum programming, subdued melodies, and few stylistic conventions.
Context: The new millennium brought about a drastic change in Autechre's style, demonstrated by Confield (2001) and Draft 7.30 (2003), as well as the Gantz Graf EP (2002). The title track from Gantz Graf inspired an iconic video by British designer Alex Rutterford, featuring an object (or an agglomeration of objects) synchronized to the music as it morphs, pulsates, shakes, and finally dissolves. Rutterford, who had previously created an unofficial video for the Tri Repetae track "Eutow" as part of the Channel 4 music programme Lo-Fi in 2001, claimed the idea for the "Gantz Graf" video came during one of his LSD trips. The second Autechre Peel session EP was also released in 2002, containing four tracks broadcast in 1999, named by John Peel himself. Autechre released two collaborative albums with Andrew M. McKenzie's Hafler Trio collective during the following three years (see collaborations). The reactions by both professional critics and fans to the release of Confield were mixed, though generally positive. According to Sean Booth, "most of Confield came out of experiments with Max that weren't really applicable in a club environment." In contrast, 2003's Draft 7.30 was seen by some as an easier record to grasp. Booth stated in an interview around the release of Draft 7.30 that "[rhythm] doesn't seem to limit us in the way it did when we first started. Now I think we just get it, we're totally fluent in it and can be more expressive." Untilted (a play on the word "untitled"), the duo's eighth album, was released in 2005. It roughly continued the sound of their previous two LPs, though featured compositions that mutated greatly during their duration, typically alternating between passages of ambience and heavily processed, precise beats, such as on "Ipacial Section". Its final track, "Sublimit", is at almost sixteen minutes Autechre's longest composition to feature on any of their albums until 2016's elseq 1-5. The release of Untilted was followed by a two-month tour that took the group around Europe, America and Japan, but withdrew them from studio work for an unusual length of time. The outcome of this, coupled with a forced change in studio setup, was a gap of three years between releases, longer than ever before.
Question: How did others feel about it?
Answer: though generally positive.

Problem: Background: Carter was born in Clifton, New Jersey, the fourth of seven children. He acquired a criminal record and was sentenced to a juvenile reformatory for assault, having stabbed a man when he was 11. Carter escaped from the reformatory in 1954 and joined the Army. A few months after completing infantry basic training at Fort Jackson, South Carolina, he was sent to West Germany.
Context: During the new trial, Alfred Bello repeated his 1967 testimony, identifying Carter and Artis as the two armed men he had seen outside the Lafayette Grill. Bradley refused to cooperate with prosecutors, and neither prosecution nor defense called him as a witness. The defense responded with testimony from multiple witnesses who identified Carter at the locations he claimed to be at when the murders happened. Investigator Fred Hogan, whose efforts had led to the recantations of Bello and Bradley, appeared as a defense witness. Hogan was asked on cross examinations whether any bribes or inducements were offered to Bello to secure his recantation, which Hogan denied. His original handwritten notes on his conversations with Bello were entered into evidence. The defense also pointed out the inconsistencies in the testimony of Patricia Valentine, and read the 1967 testimony of William Marins, who had died in 1973, noting that his descriptions of the shooters were drastically different from Artis and Carter's actual appearances. The court also heard testimony from a Carter associate that Passaic County prosecutors had tried to pressure her into testifying against Carter. Prosecutors denied the charge. After deliberating for almost nine hours, the jury again found Carter and Artis guilty of the murders. Judge Leopizzi re-imposed the same sentences on both men: a double life sentence for Carter, a single life sentence for Artis. Artis was paroled in 1981. Carter's attorneys continued to appeal. In 1982, the Supreme Court of New Jersey affirmed his convictions (4-3). While the justices felt that the prosecutors should have disclosed Harrelson's oral opinion (about Bello's location at the time of the murders) to the defense, only a minority thought this was material. The majority thus concluded that the prosecution had not withheld information that the Brady disclosure law required that they provide to the defense. According to bail bondswoman Carolyn Kelley, in 1975-1976 she helped raise funds to win a second trial for Carter, which resulted in his release on bail in March 1976. On a fund-raising trip the following month, Kelley said the boxer beat her severely over a disputed hotel bill. The Philadelphia Daily News reported the alleged beating in a front-page story several weeks later, and celebrity support for Carter quickly eroded, though Carter denied the accusation and there was insufficient evidence for legal prosecution. Mae Thelma Basket, whom Carter had married in 1963, divorced him after their second child was born, because she found out that he had been unfaithful to her.
