Bert Whyte was the producer and engineer. Ruth, his wife, was the assistant engineer. Belock and Whyte decided to record music on 35 mm magnetic film, which they believed was an improvement over half-inch tape. Westrex built this equipment to their specifications, at a cost then of about $20,000 for each recorder. Neumann U 47 microphones were purchased to go with the film recorders. Everest’s recording philosophy was to make minimally-miked three-channel recordings using 35 mm film recorders in the specially designed Belock Recording Studio in Bayside, New York and in a portable version on location in the USA and Europe. In May 1959, Edward Wallerstein (formerly president of Columbia Records) was appointed as a vice president of the company.
