Some context: Hoodoo Gurus (referred to as the Gurus by fans) are an Australian rock band, formed in Sydney in 1981, by the mainstay Dave Faulkner (songwriter, lead singer and guitarist) and later joined by Richard Grossman (bass), Mark Kingsmill (drums), and Brad Shepherd (guitar, vocals, harmonica). Their popularity peaked in the mid to late 1980s with albums Mars Needs Guitars!, Blow Your Cool! and Magnum Cum Louder.
They followed Kinky with Crank in 1994. The 'Crank' world tour took the Gurus through USA, Canada, Europe and included a one-month tour of Brazil. Faulkner also composed the soundtrack to Laurie McInnes' 1994 feature film Broken Highway. In 1995, the Gurus collaborated with The Masters Apprentices frontman Jim Keays on an updated rendition of "Turn Up Your Radio". The song was included on a new Masters' Best of album, as well as being issued as a single.  In 1996 they moved to Mushroom Records for the release of their next album, Blue Cave. The band then undertook a national tour of Australian tour with US outfit The Posies and local band Drop City. Touring commitments were curtailed when Kingsmill severed tendons and nerves in his arm as a result of an onstage accident. Once Kingsmill recovered, the Gurus completed their 'Circus Maximus' Australian tour by end of 1996. In January 1997, Faulkner announced that the band would be breaking up in December.

Some context: Gilbert "Gil" Scott-Heron (April 1, 1949 - May 27, 2011) was an American soul and jazz poet, musician, and author, known primarily for his work as a spoken-word performer in the 1970s and 1980s. His collaborative efforts with musician Brian Jackson featured a musical fusion of jazz, blues, and soul, as well as lyrical content concerning social and political issues of the time, delivered in both rapping and melismatic vocal styles by Scott-Heron. His own term for himself was "bluesologist", which he defined as "a scientist who is concerned with the origin of the blues". His music, most notably on the albums Pieces of a Man and Winter in America in the early 1970s, influenced and foreshadowed later African-American music genres such as hip hop and neo soul.
At the time of Scott-Heron's death, a will could not be found to determine the future of his estate. Additionally, Raquiyah Kelly-Heron filed papers in Manhattan, New York's Surrogate's Court in August 2013, claiming that Rumal Rackley is not Scott-Heron's son and should therefore be omitted from matters concerning the musician's estate. According to the Daily News website, Rackley, Kelly-Heron and two other sisters have been seeking a resolution to the issue of the management of Scott-Heron's estate, as Rackley stated in court papers that Scott-Heron prepared him to be the eventual administrator of the estate. Scott-Heron's 1994 album Spirits was dedicated to "my son Rumal and my daughters Nia and Gia", and in court papers Rackley added that Scott-Heron introduced me [Rackley] from the stage as his son." .  In 2011, Rackley filed a suit against sister Gia Scott-Heron and her mother, Scott-Heron's first wife, Brenda Sykes, as he believed they had unfairly attained US$250,000 of Scott-Heron's money. The case was later settled for an undisclosed sum in early 2013; but the relationship between Rackley and Scott-Heron's two adult daughters already had become strained in the months after Gil's death. In her submission to the Surrogate's Court, Kelly-Heron states that a DNA test completed by Rackley in 2011--using DNA from Scott-Heron's brother--revealed that they "do not share a common male lineage", while Rackley has refused to undertake another DNA test since that time. A hearing to address Kelly-Heron's filing was scheduled for late August 2013, but, As of March 2016, further information on the matter is not publicly available. However, Rackley still serves as court-appointed administrator for the estate, and donated material to the Smithsonian's new National Museum of African American History and Culture for Scott-Heron to be included among the exhibits and displays when the museum opened in September 2016.  According to the Daily News website, Kelly-Heron and two other sisters have been seeking a resolution to the issue of the management of Scott-Heron's estate. During the time Scott-Heron's 1994 album Spirits was being produced, he was living in Brooklyn, New York, with Nia and her mother.
