In 1972, Queen entered discussions with Trident Studios after being spotted at De La Lane Studios by John Anthony and after discussions were offered a management deal by Norman Sheffield under Neptune Productions, a subsidiary of Trident to manage the band and enable them to use the facilities at Trident to record new material whilst the management search for a record label to sign Queen. This suited both parties at the time as Trident were expanding into management and Queen under the deal were able to make use of the hi-tech recording facilities shared by bands at the time such as the Beatles and Elton John to produce new material. However, Trident found it difficult to find a label for a band bearing a name with such connotation during the early 1970s.

Bachman in 1949 made it possible for a great variety of record companies to get into the business of making long playing records. The business grew quickly and interest spread in high fidelity sound and the do-it-yourself market for pickups, turntables, amplifier kits, loudspeaker enclosure plans, and AM/FM radio tuners. The LP record for longer works, 45 rpm for pop music, and FM radio became high fidelity program sources in demand. Radio listeners heard recordings broadcast and this in turn generated more record sales. The industry flourished.
