Teachrock is a music education tool meant to teach schoolchildren (6-12) the history of music in the 20th century through the lenses of history. Much of Amercan music that was so influential that it became a genre in itself (Blues, Rock & Roll with its many incarnations, Hip Hop, etc.) was a reaction to trying times in American History Jim Crow Era, the World Wars, The Peace Movement, The Vietnam War, the Birth of the Crack Epidemic, etc. Music was not created in a vacuum.
I'm hoping that this tool catches on like wildfire, so I will be keeping my fingers crossed.
