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.
