IN: Maya Angelou ( ( listen); born Marguerite Annie Johnson; April 4, 1928 - May 28, 2014) was an American poet, singer, memoirist, and civil rights activist. She published seven autobiographies, three books of essays, several books of poetry, and was credited with a list of plays, movies, and television shows spanning over 50 years. She received dozens of awards and more than 50 honorary degrees. Angelou is best known for her series of seven autobiographies, which focus on her childhood and early adult experiences.

Marguerite Annie Johnson was born in St. Louis, Missouri, on April 4, 1928, the second child of Bailey Johnson, a doorman and navy dietitian, and Vivian (Baxter) Johnson, a nurse and card dealer. Angelou's older brother, Bailey Jr., nicknamed Marguerite "Maya", derived from "My" or "Mya Sister". When Angelou was three and her brother four, their parents' "calamitous marriage" ended, and their father sent them to Stamps, Arkansas, alone by train, to live with their paternal grandmother, Annie Henderson. In "an astonishing exception" to the harsh economics of African Americans of the time, Angelou's grandmother prospered financially during the Great Depression and World War II because the general store she owned sold needed basic commodities and because "she made wise and honest investments". Four years later, the children's father "came to Stamps without warning" and returned them to their mother's care in St. Louis. At the age of eight, while living with her mother, Angelou was sexually abused and raped by her mother's boyfriend, a man named Freeman. She told her brother, who told the rest of their family. Freeman was found guilty but was jailed for only one day. Four days after his release, he was murdered, probably by Angelou's uncles. Angelou became mute for almost five years, believing, as she stated, "I thought, my voice killed him; I killed that man, because I told his name. And then I thought I would never speak again, because my voice would kill anyone". According to Marcia Ann Gillespie and her colleagues, who wrote a biography about Angelou, it was during this period of silence when Angelou developed her extraordinary memory, her love for books and literature, and her ability to listen and observe the world around her. Shortly after Freeman's murder, Angelou and her brother were sent back to their grandmother. Angelou credits a teacher and friend of her family, Mrs. Bertha Flowers, with helping her speak again. Flowers introduced her to authors such as Charles Dickens, William Shakespeare, Edgar Allan Poe, Douglas Johnson, and James Weldon Johnson, authors who would affect her life and career, as well as black female artists like Frances Harper, Anne Spencer, and Jessie Fauset. When Angelou was 14, she and her brother moved in with their mother once again, who had since moved to Oakland, California. During World War II, Angelou attended the California Labor School. Before graduating, she worked as the first black female streetcar conductor in San Francisco. Three weeks after completing school, at the age of 17, she gave birth to her son, Clyde (who later changed his name to Guy Johnson).
QUESTION: How long did that go on for
IN: Bruce Randall Hornsby (born November 23, 1954) is an American singer and pianist. Hornsby draws frequently from classical, jazz, bluegrass, folk, Motown, gospel, rock, blues, and jam band musical traditions. Hornsby's recordings have been recognized on a number of occasions with industry awards, including the 1987 Grammy Award for Best New Artist with Bruce Hornsby and the Range, the 1990 Grammy Award for Best Bluegrass Album, and the 1994 Grammy Award for Best Pop Instrumental Performance. Hornsby has also achieved recognition for his solo albums and performances, his touring band Bruce Hornsby and the Noisemakers, his bluegrass project with Ricky Skaggs and his appearances as a session and guest musician.

Hornsby played more than 100 shows with the Grateful Dead from 1988 until Jerry Garcia's death in 1995. At some shows in 1988 and 1989, he joined the band as a special guest and played accordion or synthesizer. Starting in the fall of 1990, he played piano (and frequently accordion) at many gigs following the death of longtime Grateful Dead keyboardist Brent Mydland, who died suddenly in July 1990. Mydland's place was filled in September 1990 by Vince Welnick, who became the sole keyboardist by March 1992, although Hornsby still sat in with the band on occasion. Hornsby's own music evolved significantly during this time period. Critics have suggested that the Dead's vibrant tradition of melding folk music and the blues with psychedelic rock in "loose-knit expressions" and extended jamming "further pushed [Hornsby] outside the confines of mainstream pop." Critics have also commented upon the "close musical connection" formed between Hornsby and Jerry Garcia, suggesting that Hornsby's particular style of jazz-fueled improvisation added to the band's repertoire, and helped to revitalize and refocus Jerry Garcia's guitar solos in the band's sound. Hornsby's friendship with Garcia continued, both inside and outside the band, as the two "challenged" each other to expand their musicianship through several other album and live collaborations. Above all, Hornsby's musical versatility and ability to slip in and out of extended freeform jams won over longtime Grateful Dead fans. Since his first involvement with the Grateful Dead, Hornsby's live shows have drawn Deadheads and Hornsby has commented: "I've always liked the group of fans that we've drawn from the Grateful Dead time, because those fans are often adventurous music listeners." He has performed a number of their songs at his concerts and as homages on studio and live albums, while Hornsby originals "The Valley Road," and "Stander on the Mountain," appeared several times in the Dead's setlists. Hornsby also co-performed the improvisation "Silver Apples of the Moon" for the Grateful Dead's Infrared Roses. Hornsby was the presenter when the Grateful Dead were inducted into the Rock and Roll Hall of Fame in 1994 and in 2005 he participated in "Comes a Time", a tribute concert to Jerry Garcia. He continues to work with Dead-related projects, such as Bob Weir's Ratdog, Mickey Hart's solo projects. He performed as part of The Other Ones in 1998 and 2000, and on occasion sat in with The Dead. Hornsby continues to be involved in the Grateful Dead and Furthur community, having opened All Good Music Festival in 2012 featured with Bob Weir on rhythm guitar. In mid-2013, Hornsby performed with Grateful Dead-influenced bluegrass group Railroad Earth. Hornsby reunited with surviving members of the Grateful Dead along with Trey Anastasio from Phish and Jeff Chimenti at Levi's Stadium in Santa Clara, California, and later at Soldier Field in Chicago, Illinois, in July 2015.
