Problem: Background: Sun Ra (born Herman Poole Blount, legal name Le Sony'r Ra; May 22, 1914 - May 30, 1993) was an American jazz composer, bandleader, piano and synthesizer player, and poet known for his experimental music, "cosmic" philosophy, prolific output, and theatrical performances. For much of his career, Ra led "The Arkestra", an ensemble with an ever-changing name and flexible line-up. Born and raised in Alabama, Blount eventually became involved in the Chicago jazz scene during the 1940s. He soon abandoned his birth name, taking the name Sun Ra (after Ra, the Egyptian God of the Sun) and developing a complex persona and mythology that would make him a pioneer of Afrofuturism: he claimed he was an alien from Saturn on a mission to preach peace, and throughout his life he consistently denied any ties to his prior identity.
Context: Sun Ra's world view was often described as a philosophy, but he rejected this term, describing his own manner as an "equation" and saying that while philosophy was based on theories and abstract reasoning, his method was based on logic and pragmatism. Many of the Arkestra cite Sun Ra's teachings as pivotal and for inspiring such long-term devotion to the music that they knew would never make them much money. His equation was rarely (if ever) explained as a whole; instead, it was related in bits and pieces over many years, leading some to doubt that he had a coherent message. However, Martinelli argues that, when considered as a whole, one can discern a unified world view that draws upon many sources, but is also unique to Sun Ra, writing:  Sun Ra presents a unified conception, incorporating music, myth, and performance into his multi-leveled equations. Every aspect of the Sun Ra experience, from business practices like Saturn Records to published collections of poetry to his 35-year career in music, is a manifestation of his equations. Sun Ra seeks to elevate humanity beyond their current earthbound state, tied to outmoded conceptions of life and death when the potential future of immortality awaits them. As Hall has put it, "In this era of 'practical' things men ridicule even the existence of God. They scoff at goodness while they ponder with befuddled minds the phantasmagoria of materiality. They have forgotten the path which leads beyond the stars."  He drew on sources as diverse as the Kabbalah, Rosicrucianism, channeling, numerology, Freemasonry, Ancient Egyptian Mysticism, and black nationalism. Sun Ra's system had distinct Gnostic leanings, arguing that the god of most monotheistic religions was not the creator god, not the ultimate god, but a lesser, evil being. Sun Ra was wary of the Bible, knowing that it had been used to justify slavery. He often re-arranged and re-worded Biblical passages (and re-worked many other words, names, or phrases) in an attempt to uncover "hidden" meanings. The most obvious evidence of this system was Ra's practice of renaming many of the musicians who played with him.  Bassoonist/multireedist James Jacson had studied Zen Buddhism before joining Sun Ra and identified strong similarities between Zen teachings and practices (particularly Zen koans) and Ra's use of non sequiturs and seemingly absurd replies to questions. Drummer Art Jenkins admitted that Sun Ra's "nonsense" sometimes troubled his thoughts for days until inspiring a sort of paradigm shift, or profound change in outlook. Drummer Andrew Cyrille said Sun Ra's comments were "very interesting stuff... whether you believed it or not. And a lot of times it was humorous, and a lot of times it was ridiculous, and a lot of times it was right on the money."  Some of Sun Ra's songs with words featured lyrics that although simple, were inspirational and philosophical. The most famous example was "Space Is the Place!" Another example was the song that went, "You made a mistake. You did something wrong. Make another mistake, and do something right!" Sometimes (typically at the end of a set) the entire Arkestra snaked out through the audience, playing and chanting something like this.
Question: What is an example of a famous performance he gave?
Answer: The most famous example was "Space Is the Place!"

Background: Usher was born in Dallas, Texas, the son of Jonetta Patton (nee O'Neal), from Tennessee, and Usher Raymond III.

Usher grew up with his mother, then-stepfather, and half-brother, James Lackey (born 1984).

Context: On October 16, 2015, Usher released an interactive music video exclusively on the music streaming platform Tidal called "Chains" that featuring artist Nas and Bibi Bourelly. "Chains" literally forces the viewer to confront the issue of racial profiling and police brutality head-on: By utilizing the webcam on the viewer's computer as well as facial recognition technology, "Chains" paused mid-song whenever the viewer's eyes deviate from the video. Usher performed the song for the first time at the Tidal X:1020 concert on October 20, 2015, at Brooklyn's Barclays Arena. On January 14, 2016, after continual delays of his eighth album, Usher announced via Daniel Arsham Instagram post that he changed the title of the album from UR to Flawed.

On June 12, 2016, it was reported that Raymond signed a management deal with business partner Scooter Braun. Braun already represented Justin Bieber and had a joint venture with Raymond and Bieber. This report was confirmed by Usher during a sit down interview with Ryan Seacrest at the 73rd annual Cannes Festival on June 21, 2016. Usher furthered his acting career, starring as American former professional boxer Sugar Ray Leonard in the 2016 American-Panamanian biographical sports film Hands of Stone about the career of Panamanian former professional boxer Roberto Duran.

On August 30, "Rivals" featuring Future was released and debuted exclusively on Tidal with its accompanying video. It was released on Vevo on September 2, 2016. On September 13, 2016, both "Missin U" and "Rivals" were sent to radio as the album's third and fourth singles.  The album Hard II Love was released on September 16, 2016, and received generally positive reviews from contemporary music critics. It debuted at number 5 on the US Billboard 200, and sold 28,000 copies in the United States in its first week. It also became his seventh consecutive top ten album in the United States. The lead single, "No Limit" featuring rapper Young Thug initially was serviced to Urban radio on June 9, and eventually peaked at number 32 on the Billboard Hot 100, and number 9 on the Hot R&B/Hip-Hop Songs.
