The world is a whirr with notions of authenticity ... we seek this elusive quality in music, fashion literature and movies.
Like that mysterious element known as "cool", authenticity appears to just exist without need for explanation. Either something has it or does not - unless the marketing team have decided to create it.
Music has been trading in this quality for a long time and now a performer without a traumatic back story will struggle to appear authentic. The stint in rehab, the succession of failed relationships, failed failures, lost weekends and tales of addiction and despair are now essential to having a media profile and getting noticed.
There seems to be a strange sort of race to have the most tragic story in the chase for authenticity. That is not to diminish the trials many artists go through in order to create their music but what is now almost a compulsory requirement to have had a really tough time in the face of general indifference has become an essential accessory.
The question: "Can white men sing the blues" still rattles the cage of authenticity. The lives and music of people such as BB King, Muddy Waters and Robert Johnson have captured the hardship of being a black man in a white man's world, where danger and prejudice dictate life.
