US researcher and first-time guest Sean McCann drops by to share his research into yet more family links between popular music's heavy hitters, and the military machine.

We begin by discussing Music Row in Nashville, a small, compact part of town which was the real powerhouse behind the County music industry - rather similar to Laurel Canyon's influence on the folk rock scene - and with Establishment connections aplenty. Out of Nashville came the Grand Ole Opry, a long-running radio showcase of Country acts, utilising some revolutionary technology of the time.

This moves us on to the roots of the American radio industry, originally developed by the US Navy. Out of this institution came RCA, the Radio Corporation of America, which spearheaded many of the standards in vinyl record production, and spawned the RCA record label, through which many prominent music artists were promoted.

Sean's data builds on information unleashed earlier in the series, all adding weight to the notion that popular culture and entertainment have long been a military-grade weapon in the mind-control of the masses.
