Some context: Kwame Nkrumah PC (21 September 1909 - 27 April 1972) was a Ghanaian politician and revolutionary. He was the first prime minister and president of Ghana, having led it to independence from Britain in 1957. An influential advocate of Pan-Africanism, Nkrumah was a founding member of the Organization of African Unity and winner of the Lenin Peace Prize in 1962. After twelve years abroad pursuing higher education, developing his political philosophy, and organizing with other diasporic pan-Africanists, Nkrumah returned to Gold Coast to begin his political career as an advocate of national independence.
Beginning in April 1949, there was considerable pressure on Nkrumah from his supporters to leave the UGCC and form his own party. On 12 June 1949, he announced the formation of the Convention People's Party (CPP), with the word "convention" chosen, according to Nkrumah, "to carry the masses with us." There were attempts to heal the breach with the UGCC; at one July meeting, it was agreed to reinstate Nkrumah as secretary and disband the CPP. But Nkrumah's supporters would not have it, and persuaded him to refuse the offer and remain at their head.  The CPP adopted the red cockerel as its symbol - a familiar icon for local ethnic groups, and a symbol of leadership, alertness, and masculinity. Party symbols and colours (red, white, and green) appeared on clothing, flags, vehicles, and houses. CPP operatives drove red-white-and-green vans across the country, playing music and rallying public support for the party and especially for Nkrumah. These efforts were wildly successful, especially because previous political efforts in the Gold Coast had focused exclusively on the urban intelligentsia.  The British convened a selected commission of middle-class Africans, including all of the Big Six except Nkrumah, to draft a new constitution that would give Ghana more self-government. Nkrumah saw, even before the commission reported, that its recommendations would fall short of full dominion status, and began to organise a Positive Action campaign. Nkrumah demanded a constituent assembly to write a constitution. When the governor, Charles Arden-Clarke, would not commit to this, Nkrumah called for Positive Action, with the unions beginning a general strike to begin on 8 January 1950. The strike quickly led to violence, and Nkrumah and other CPP leaders were arrested on 22 January, and the Evening News was banned. Nkrumah was sentenced to a total of three years in prison, and he was incarcerated with common criminals in Accra's Fort James.  Nkrumah's assistant, Komla Agbeli Gbedemah, ran the CPP in his absence; the imprisoned leader was able to influence events through smuggled notes written on toilet paper. The British prepared for an election for the Gold Coast under their new constitution, and Nkrumah insisted that the CPP contest all seats. The situation had become calmer once Nkrumah was arrested, and the CPP and the British worked together to prepare electoral rolls. Nkrumah stood, from prison, for a directly-elected Accra seat. Gbedemah worked to set up a nationwide campaign organisation, using vans with loudspeakers to blare the party's message. The UGCC failed to set up a nationwide structure, and proved unable to take advantage of the fact that many of its opponents were in prison.  In the February 1951 legislative election, the first general election to be held under universal franchise in colonial Africa, the CPP was elected in a landslide. The CPP secured 34 of the 38 seats contested on a party basis, with Nkrumah elected for his Accra constituency. The UGCC won three seats, and one was taken by an independent. Arden-Clarke saw that the only alternative to Nkrumah's freedom was the end of the constitutional experiment. Nkrumah was released from prison on 12 February, receiving a rapturous reception from his followers. The following day, Arden-Clarke sent for him and asked him to form a government.

Some context: 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.
Sun Ra soon left college because, he claimed, he had a visionary experience as a college student that had a major, long-term influence on him. In 1936 or 1937, in the midst of deep religious concentration, Sun Ra claimed that a bright light appeared around him, and, as he later said:  My whole body changed into something else. I could see through myself. And I went up... I wasn't in human form... I landed on a planet that I identified as Saturn... they teleported me and I was down on [a] stage with them. They wanted to talk with me. They had one little antenna on each ear. A little antenna over each eye. They talked to me. They told me to stop [attending college] because there was going to be great trouble in schools... the world was going into complete chaos... I would speak [through music], and the world would listen. That's what they told me.  Sun Ra said that this experience occurred in 1936 or 1937. According to Szwed, the musician's closest associates cannot date the story any earlier than 1952. (Sun Ra also said that the incident happened when he was living in Chicago, where he did not settle until the late 1940s). Sun Ra discussed the vision, with no substantive variation, to the end of his life. His trip to Saturn allegedly occurred a full decade before flying saucers entered public consciousness with the 1947 encounter of Kenneth Arnold. It was earlier than other public accounts: about 15 years before George Adamski wrote about contact with benevolent beings; and almost 20 years before the 1961 case of Barney and Betty Hill, who recounted sinister UFO abductions. Szwed says that, "even if this story is revisionist autobiography... Sonny was pulling together several strains of his life. He was both prophesizing his future and explaining his past with a single act of personal mythology."
