A companion to the 2015-2016 Country Music Hall of Fame exhibit of the same name, Dylan, Cash and the Nashville Cats: A New Music City is a double-disc history of the moment when country met rock – or when rock met country, as the case might be. In this particular reading of country-rock history, the movement begins in 1966, when Bob Dylan headed down to Nashville to cut Blonde on Blonde with a crew of the city's renowned studio musicians. Prior to that, country could be heard in rock & roll mainly through rockabilly, a music that functions as prehistory on this collection, present through the presence of Sun veteran Johnny Cash but not much else.
