Jack DeJohnette (born 9 August 1942) is an American jazz drummer, pianist, and composer. An important figure of the fusion era of jazz, DeJohnette is one of the most influential jazz drummers of the 20th century, due to extensive work as leader and sideman for musicians like Miles Davis, Joe Henderson, Freddie Hubbard, Keith Jarrett, Sonny Rollins, and John Scofield.

DeJohnette was born on 9 August 1942 in Chicago, Illinois. He began his musical career as a piano player, studying from age four and beginning to play professionally at age 14, but he decided to forsake it and took on the drums as his main instrument. DeJohnette would later credit an uncle, Roy I. Wood Sr., as the person in his life who inspired him to play music. Wood was a Chicago disc jockey who would later become vice president of the National Network of Black Broadcasters.

DeJohnette began his drumming career playing R&B, hard bop, and avant-garde music in Chicago, leading his own groups while playing also with Richard Abrams and Roscoe Mitchell, both of whom were members of the Association for the Advancement of Creative Musicians. In the early 1960s, Dejohnette had the opportunity to perform with John Coltrane and his quintet, an early foray into playing with big name jazz musicians.

Ken Boothe OD (born 22 March 1948, Denham Town, Kingston, Jamaica) is a Jamaican recording artist.

Ken Boothe was born in the Denham Town area of Kingston in 1948, the youngest of seven children, and began singing in school. His recording career began in the late 1950s when he formed a duo with his neighbour Stranger Cole as 'Stranger & Ken', the first tracks released by them being "Hush Baby" on the B-side of Cole's Island Records single "Last Love", and the "Thick in Love" single on R&B Records, both in 1963. They released several more popular singles between 1963 and 1965, including "World's Fair", "Hush", and "Artibella". Boothe also recorded as a duo with Roy Shirley (as Roy & Ken), releasing the "Paradise" single in 1966.

His first solo tracks were recorded in 1966 after Clement "Coxsone" Dodd had signed him to the Studio One Label. He also recorded material for Phil Pratt and Sonia Pottinger the same year. He had almost immediate success with songs like "The Train Is Coming" (on which he was backed by The Wailers) and "Lonely Teardrops" and by the following year, Boothe and Alton Ellis had a successful UK tour with the Studio One session group, The Soul Vendors. Boothe was promoted as "Mr. Rock Steady" by Dodd during this period. Boothe continued to record for Dodd until 1970, when he switched to Leslie Kong's Beverley's Records, where his success continued with hits such as "Freedom Street" and "Why baby Why".
