Some context: Marc Alexander Hunter was born in Taumarunui on 7 September 1953. In the late 1950s his family performed publicly where his father, Stuart, played saxophone, his mother, Voi, on piano and his older brother, Todd Hunter (born 1951), on guitar with Marc providing drums. He also grew up with two younger brothers, Ross and Brett. Hunter remembered, "We got guitars for Christmas one year, I broke mine but Todd played his.
Marc Hunter travelled overseas to recuperate, he visited Morocco and London. Back in Australia he signed a recording deal with CBS, which issued his debut solo album, Fiji Bitter, in November 1979. For the sessions he used Todd on bass guitar, John Annas on drums (ex-Kevin Borich Express), Harvey James on guitar (from Sherbet), and Terry Wilson on guitar (ex-Original Batter-sea Heroes, Wasted Daze).  Fiji Bitter was recorded at Studio 301, Sydney with Richard Lush producing and engineering - Hunter wrote or co-wrote most of its tracks. The album's lead single, "Island Nights" (July), peaked at No. 20. He formed Marc Hunter and the Romantics, with Annas and James, to promote the album. Two more singles, "Don't Take Me" (November) and "When You Walk in the Room" (January 1980), appeared - neither reached the top 50.  In 1980 Hunter, on lead vocals, formed an R&B group in Sydney, the Headhunters, with Todd on bass guitar (by then ex-Dragon), Kevin Borich on guitar, Mick Cocks on guitar (ex-Rose Tattoo), John Watson on drums (ex-Kevin Borich Express). Australian musicologist, Ian McFarlane, described them as "an ad hoc aggregation of musicians who were drawn together by a love of playing raucous R&B".  Hunter resumed his solo career with his second album, Big City Talk, which appeared in August 1981 on PolyGram/Mercury labels. It was co-produced by Hunter and Todd. Debbie Muir of The Canberra Times, felt it "covered a wide range of material that bore some resemblance to his last album, Fiji Bitter, but was totally different to his old, Dragon days." He had used session musicians: Borich, Dave Mason (of The Reels) and Mark Punch (ex-Renee Geyer Band). Muir's fellow journalist at The Canberra Times, Garry Raffaele, opined that it "is flat, directionless, unexciting, effete rock and roll. It is devoid of feeling."  On working as a solo artist, he declared, "I am happier now on my own. I was in a wretched state of mind when I was in the band... I miss the camaraderie involved but then I prefer to make my own decisions." The title track, "Big City Talk", was released as a single in July and reached No. 25. Follow up singles, "(Rock'n'Roll is) a Loser's Game" (September), "Side Show" (November) and "Nothing but a Lie" (May 1982) did not chart. In 1981 he formed the Marc Hunter Band and in October they toured Australia with Renee Geyer; the set included a duet by Hunter and Geyer. During 1982 Hunter was working with US-born keyboardist and record producer, Alan Mansfield. In March of that year he was arrested for "$4500 in unpaid parking fines", he described his jail cell as "unbelievably filthy."

Some context: Brian Wayne Transeau (born October 4, 1971), better known by his stage name BT, is an American music producer, composer, technologist, audio technician, multi-instrumentalist, singer, and songwriter. An artist in the electronica music genre, he is credited as a pioneer of the trance and intelligent dance music styles that paved the way for EDM, and for "stretching electronic music to its technical breaking point." He also creates music within many other styles, such as classical, film composition and bass music. BT is also known for pioneering the stutter edit.
In the early years of BT's career, he became a pioneering artist in the trance genre, this despite the fact that he doesn't consider himself a DJ, since he infrequently spins records and comes from an eclectic music background. He was creating trance music before it was known by that name. When he started out, such common elements as a build, breakdown and drop were unclassified. BT's was a unique interpretation of what electronic music could be. His first trance recordings, "A Moment of Truth" and "Relativity", became hits in dance clubs in the UK. His productions were not yet popular in the US, and he was initially unaware that he had become popular across the Atlantic, where UK DJs like Sasha were regularly spinning his music for crowds. Sasha bought BT a ticket to London, where BT witnessed his own success in the clubs, with several thousand clubbers responding dramatically when Sasha played BT's song. He also met Paul Oakenfold, playing him tracks that would make up his first album. He was quickly signed to Oakenfold's record label, a subsidiary of Warner Brothers.  BT's 1995 debut album Ima, released on Oakenfold's label, was a progressive house effort. The opening track, "Nocturnal Transmission", was featured in The Fast and the Furious. The album also featured a song with Vincent Covello. Blending house beats with sweeping New Age sounds, Ima helped to create the trance sound. "Ima (Jin )" is the Japanese word for "now". BT has stated that it also means many other things and that the intention of the album is to have a different effect for everyone.  Following the release of Ima, BT began traveling to England regularly. It was during this time that he met Tori Amos. They would collaborate on his song "Blue Skies", which reached the number one spot on Billboard magazine's Dance Club Songs chart in January 1997. This track helped expand BT's notability beyond Europe, into North America. He soon began to produce songs for well-known artists such as Sting, Madonna, Seal, Sarah McLachlan, NSYNC, Britney Spears, Diana Ross and Mike Oldfield.
