Problem: Background: 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.
Context: 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.

Problem: Background: The Rock and Roll Hall of Fame, located on the shore of Lake Erie in downtown Cleveland, Ohio, recognizes and archives the history of the best-known and most influential artists, producers, engineers, and other notable figures who have had some major influence on the development of rock and roll. The Rock and Roll Hall of Fame Foundation was established on April 20, 1983, by Atlantic Records founder and chairman Ahmet Ertegun. In 1986, Cleveland was chosen as the Hall of Fame's permanent home. Since opening in September 1995, the "Rock Hall" - part of the city's redeveloped North Coast Harbor - has hosted more than 10 million visitors and had a cumulative economic impact estimated at more than $1.8 billion.
Context: The Rock and Roll Hall of Fame and Museum produces numerous public programs, including concerts, interviews, lectures, film screenings, and other events that help tell the story of rock and roll. Every February, the museum celebrates Black History Month by hosting concerts, film screenings and lectures that illustrate the important role African-Americans have played in the history of rock and roll. Since the program began in 1996, such artists as Robert Lockwood, Jr., the Temptations, Charles Brown, Ruth Brown, the Ohio Players, Lloyd Price, Little Anthony and the Imperials, and Al Green have appeared at the museum during Black History Month. Another program is the Hall of Fame Series. This series began in April 1996 and features interviews with Hall of Fame inductees in a rare and intimate settings, most often in the Museum's Foster Theater. The interviews are usually followed by a question-and-answer session with the audience and, often, a performance by the inductee. Among the inductees who have taken part in this series are Darryl "DMC" McDaniels of Run-D.M.C., Lloyd Price, Marky Ramone, Seymour Stein, Ray Manzarek of the Doors, Ronnie Spector, Bootsy Collins, Ann and Nancy Wilson of Heart, and Jorma Kaukonen of the Jefferson Airplane. A similar program is the Legends Series. The only real difference between this program and the Hall of Fame Series is that it features artists who have not yet been inducted into the Hall of Fame. Peter Hook of Joy Division, Spinderella of Salt n Pepa, Tommy James, and the Chi-Lites are among the artists who have participated in the Legends Series. The Rock and Roll Hall of Fame and Museum's most acclaimed program is the annual American Music Masters series. Each year the museum celebrates one of the Hall's inductees with a week-long series of programs that include interviews, film screenings, and, often, a special exhibit. The celebration ends with an all-star concert held at a Cleveland theater. The concerts include a diverse mix of artists, from Hall of Fame inductees to contemporary musicians. The American Music Masters series began in 1996 with Hard Travelin': The Life and Legacy of Pete Seeger. Since then, the programs have honored the following inductees: Jimmie Rodgers (1997), Robert Johnson (1998), Louis Jordan (1999), Muddy Waters (2000), Bessie Smith (2001), Hank Williams (2002), Buddy Holly (2003), Lead Belly (2004), Sam Cooke (2005), Roy Orbison (2006), Jerry Lee Lewis (2007), Les Paul (2008), Janis Joplin (2009), Fats Domino and Dave Bartholomew (2010), Aretha Franklin (2011), and Chuck Berry (2012).
