Watch any one of the Crossroads Guitar Festivals, DVDs or on you tube, there are lots of hero's out there now it's just that there are no more record companies willing to risk the cost of studio time and all the other expenses to make what may not return them any money. I would suggest that you invest in the music that interest's you by buying the CD's or Downloading the the artists that you like and thus helping them keep on making music. The world has changed, artists are no longer supported until they can earn their way. Now it has to be done by word of mouth.
We have the ability to make the next Guitar Hero, but it won't be done on a chart it will be done through social media.
