input: When his drummer Sonny Greer was invited to join the Wilber Sweatman Orchestra in New York City, Ellington made the fateful decision to leave behind his successful career in Washington, D.C., and move to Harlem, ultimately becoming part of the Harlem Renaissance. New dance crazes such as the Charleston emerged in Harlem, as well as African-American musical theater, including Eubie Blake's Shuffle Along. After the young musicians left the Sweatman Orchestra to strike out on their own, they found an emerging jazz scene that was highly competitive and hard to crack. They hustled pool by day and played whatever gigs they could find. The young band met stride pianist Willie "The Lion" Smith, who introduced them to the scene and gave them some money. They played at rent-house parties for income. After a few months, the young musicians returned to Washington, D.C., feeling discouraged.  In June 1923, a gig in Atlantic City, New Jersey, led to a play date at the prestigious Exclusive Club in Harlem. This was followed in September 1923 by a move to the Hollywood Club - 49th and Broadway - and a four-year engagement, which gave Ellington a solid artistic base. He was known to play the bugle at the end of each performance. The group was initially called Elmer Snowden and his Black Sox Orchestra and had seven members, including trumpeter James "Bubber" Miley. They renamed themselves The Washingtonians. Snowden left the group in early 1924 and Ellington took over as bandleader. After a fire, the club was re-opened as the Club Kentucky (often referred to as the Kentucky Club).  Ellington made eight records in 1924, receiving composing credit on three including "Choo Choo". In 1925, Ellington contributed four songs to Chocolate Kiddies starring Lottie Gee and Adelaide Hall, an all-African-American revue which introduced European audiences to African-American styles and performers. Duke Ellington and his Kentucky Club Orchestra grew to a group of ten players; they developed their own sound by displaying the non-traditional expression of Ellington's arrangements, the street rhythms of Harlem, and the exotic-sounding trombone growls and wah-wahs, high-squealing trumpets, and sultry saxophone blues licks of the band members. For a short time soprano saxophonist Sidney Bechet played with them, imparting his propulsive swing and superior musicianship to the young band members.

Question: Kennedy was born as Myles Richard Bass on November 27, 1969 in Boston, Massachusetts, and subsequently lived in Northern Idaho. As a child, he moved to Spokane, Washington, where he grew up in a Christian Science family on a farm. His father, Richard Bass, died when he was four years old and his mother subsequently went on to marry a Methodist minister, and the family took the surname Kennedy. Before Kennedy attended Mead High School (which he attended with football player Jason Hanson), he found musical inspiration from Led Zeppelin, Marvin Gaye, Stevie Wonder, and John Sykes' Blue Murder band.

Kennedy has become very well known for his collaborations with Guns N' Roses lead guitarist Slash. In late 2009, it was reported that they would be working together on Slash's self-titled debut solo album. Slash later confirmed that Kennedy was chosen to sing and co-write the final song, "Starlight", on his album. Other musicians who appeared on the album include Ozzy Osbourne, Adam Levine of Maroon 5, Dave Grohl of the Foo Fighters, Kid Rock, and Chris Cornell of Soundgarden. Then, according to MusicRadar, Slash asked Kennedy to co-write and sing another song, "Back from Cali", which was added to the album at the last minute, making him the only musician to appear on more than one song on the album's standard track listing. The album was released in April 2010.  On February 3, 2010, Slash announced that Kennedy would be the lead vocalist for his band on tour. On tour, Kennedy performed a number of songs found throughout Slash's catalog. Slash and Kennedy were also the supporting act on Ozzy Osbourne's tour in 2010. The other members of Slash's band are rhythm guitarist Bobby Schneck (replaced as of the Apocalyptic Love tour with Frank Sidoras), bassist Todd Kerns (formerly of Age of Electric), and drummer Brent Fitz (formerly of Theory of a Deadman). In late 2010, Kennedy and Slash appeared on That Metal Show, a talk show on VH1 Classic. On November 14, 2011, Slash released a concert film and live album titled Made in Stoke 24/7/11 featuring Kennedy and the rest of his band.  Slash's second solo album featured Myles Kennedy, this time as the sole vocalist. It was also announced that band mates Bobby Schneck, Todd Kerns, and Brent Fitz, along with Slash, would complete the lineup for the album. In an interview with MusicRadar, Slash confirmed that it would be less of an actual solo album and more of a collaboration album with Kennedy, and that he was not sure if the album will be billed to Slash or a new name entirely. As of December 2011, three songs had been recorded: "Halo", "Standing in the Sun", and "Bad Rain". Slash has described the music as "very heavy". The album was released on May 22, 2012. A behind-the-scenes video was also released with this announcement. Titled Apocalyptic Love, the album will be billed to "Slash featuring Myles Kennedy and the Conspirators", featuring Kennedy, Kerns, and Fitz as members of Slash's band. The band performed the album in its entirety on April 11, 2012, at the Revolver Golden God Awards. The first single, "You're a Lie", was released to rock radio on February 27, 2012; a 30-second preview of the song was released online. Kennedy has reportedly said that some of the lyrics on the album are about his earlier experiences with drugs. On April 14, 2012, Kennedy performed three Guns N' Roses songs with five former members of Guns N' Roses during their Rock and Roll Hall of Fame induction in Axl Rose's absence. In 2013, he also toured with Kings of Chaos, along with Slash and other ex-Guns N' Roses members. The band's second collective album World on Fire is produced by Michael "Elvis" Baskette and was released on September 16, 2014.
