What makes a superstar? It may not be in having a perfectly in tune, beautifully modulated voice but rather in having a unique voice that is instantly recognisable and Johnny Cash always stood out from the crowd. In the early 1960s, the LP was a newish concept and Columbia wanted Johnny Cash to record some thematic albums, which was music to his ears. He started with an album of hymns and then one of train songs. In 1962 he paid homage to the working man with his fabulous ‘Blood, Sweat and Tears’.
