Told with style and pizzazz, the rousing documentary Thunder Soul celebrates the Kashmere Stage Band, a worldwide sensation in the 1970s that will forever change the way you think about high school bands. When Conrad O. Johnson, a music teacher at a predominantly black high school in Houston, replaced the staid stage band standards with contemporary funk, jazz, and original compositions, he changed the lives of his students forever. Not only did they become one of the best bands, professional or amateur, around, but they learned lessons that stayed with them long after graduation, as evidenced thirty-five years later, when the band reunited to pay tribute to the man who made it all possible.
