How many times have you read about a cool new band who are about to change the face of music forever, usher in a revolution in popular culture and destroy everything we thought we once knew about art, style and ideology? How often does excitement fade to envious bemusement upon hearing the band’s EP and realising that we haven’t finally discovered the next Velvet Underground or The Clash, but rather a new King’s of Leon, if the King’s of Leon came from Hertfordshire and the singer’s mum writes for The Guardian. Sometimes, the hype machine is turned on before a band has even played a gig or released a demo. A band can have created less musical output than an average 7 year old with a new recorder, yet can still command the attention of the music press. Many new, undiscovered bands quite rightly wonder why they remain unknown while other, equally shit bands are showered in praise and press coverage. The answer, of course, is PR.
