Problem: Charles Mingus Jr. (April 22, 1922 - January 5, 1979) was an American jazz double bassist, pianist, composer and bandleader. His compositions retained the hot and soulful feel of hard bop, drawing heavily from black gospel music and blues, while sometimes containing elements of Third Stream, free jazz, and classical music. He once cited Duke Ellington and church as his main influences. Mingus espoused collective improvisation, similar to the old New Orleans jazz parades, paying particular attention to how each band member interacted with the group as a whole.

In 1959 Mingus and his jazz workshop musicians recorded one of his best-known albums, Mingus Ah Um. Even in a year of standout masterpieces, including Dave Brubeck's Time Out, Miles Davis's Kind of Blue, John Coltrane's Giant Steps, and Ornette Coleman's prophetic The Shape of Jazz to Come, this was a major achievement, featuring such classic Mingus compositions as "Goodbye Pork Pie Hat" (an elegy to Lester Young) and the vocal-less version of "Fables of Faubus" (a protest against segregationist Arkansas governor Orval E. Faubus that features double-time sections). Also during 1959, Mingus recorded the album Blues & Roots, which was released the following year. As Mingus explained in his liner notes: "I was born swinging and clapped my hands in church as a little boy, but I've grown up and I like to do things other than just swing. But blues can do more than just swing." Mingus witnessed Ornette Coleman's legendary--and controversial--1960 appearances at New York City's Five Spot jazz club. He initially expressed rather mixed feelings for Coleman's innovative music: "...if the free-form guys could play the same tune twice, then I would say they were playing something...Most of the time they use their fingers on the saxophone and they don't even know what's going to come out. They're experimenting." That same year, however, Mingus formed a quartet with Richmond, trumpeter Ted Curson and multi-instrumentalist Eric Dolphy. This ensemble featured the same instruments as Coleman's quartet, and is often regarded as Mingus rising to the challenging new standard established by Coleman. The quartet recorded on both Charles Mingus Presents Charles Mingus and Mingus. The former also features the version of "Fables of Faubus" with lyrics, aptly titled "Original Faubus Fables". Only one misstep occurred in this era: 1962's Town Hall Concert. An ambitious program, it was plagued with troubles from its inception. Mingus's vision, now known as Epitaph, was finally realized by conductor Gunther Schuller in a concert in 1989, 10 years after Mingus's death.

Were there any other songs on the album

Answer with quotes:

Problem: Francois-Marie Arouet (French: [fRa.swa ma.Ri aR.we]; 21 November 1694 - 30 May 1778), known by his nom de plume Voltaire (; French: [vol.te:R]), was a French Enlightenment writer, historian and philosopher famous for his wit, his attacks on the established Catholic Church and Christianity as a whole and his advocacy of freedom of religion, freedom of speech and separation of church and state.

The author adopted the name Voltaire in 1718, following his incarceration at the Bastille. Its origin is unclear. It is an anagram of AROVET LI, the Latinized spelling of his surname, Arouet, and the initial letters of le jeune ("the young"). According to a family tradition among the descendants of his sister, he was known as le petit volontaire ("determined little thing") as a child, and he resurrected a variant of the name in his adult life. The name also reverses the syllables of Airvault, his family's home town in the Poitou region. Richard Holmes supports the anagrammatic derivation of the name, but adds that a writer such as Voltaire would have intended it to also convey connotations of speed and daring. These come from associations with words such as voltige (acrobatics on a trapeze or horse), volte-face (a spinning about to face one's enemies), and volatile (originally, any winged creature). "Arouet" was not a noble name fit for his growing reputation, especially given that name's resonance with a rouer ("to be beaten up") and roue (a debauche). In a letter to Jean-Baptiste Rousseau in March 1719, Voltaire concludes by asking that, if Rousseau wishes to send him a return letter, he do so by addressing it to Monsieur de Voltaire. A postscript explains: "J'ai ete si malheureux sous le nom d'Arouet que j'en ai pris un autre surtout pour n'etre plus confondu avec le poete Roi", (I was so unhappy under the name of Arouet that I have taken another, primarily so as to cease to be confused with the poet Roi.) This probably refers to Adenes le Roi, and the 'oi' diphthong was then pronounced like modern 'ouai', so the similarity to 'Arouet' is clear, and thus, it could well have been part of his rationale. Voltaire is known also to have used at least 178 separate pen names during his lifetime.

Why did he decide to change his name?
