This Saturday, 26 Chicago Public Schools teachers will gather to expand their music education background and rock out with their peers. To ensure all of their students have an opportunity to have music programs that are as diverse as they are, the educators are training on a new and innovative music program — Modern Band. The program is part of a burgeoning national movement pioneered by Little Kids Rock, a leading provider of free instruments and music instruction to U.S. public schools. Little Kids Rock currently operates in more than 1,700 schools in 127 school districts in the United States, and has served more than 500,000 students since 2002.
