Quantum Jump was a British jazz-rock band formed in 1973 at Farmyard studios by Trevor Morais and Jeffrey Levinson. The group consisted of Rupert Hine on vocals and keyboards, Mark Warner on guitar, John G. Perry on bass, and Trevor Morais on drums. The name Quantum Jump originated from a conversation between Rupert Hine and Anthony Stern about the quantum leap concept in physics. Their debut album Quantum Jump was written and arranged in 1973–1974 and recorded with rented equipment at Farmyard studios. Produced by Rupert Hine, the sessions were financed independently but later sold to The Electric Record Company due to management issues. The band's breakthrough came with their single "The Lone Ranger", which was initially released in 1976. Despite being chosen as BBC Radio 1's Album of the Week, it was banned by the BBC for containing references to drugs and homosexuality, preventing it from charting. Mark Warner left Quantum Jump in 1977 to join Cat Stevens' live band, leading to the release of their second album Barracuda that same year. The group disbanded at the end of 1977 due to poor sales but reunited in 1979 when a re-release of "The Lone Ranger" became a hit, peaking at Number 5 on the UK Singles Chart and Number 67 in Australia. This success led to the release of their third album Mixing, a collection of remixed tracks from their previous albums.
