Frank Zappa is an outstanding figure in Western musical, cultural and even political life of the twentieth century, with a musical legacy of extraordinary stylistic breadth and complexity. His musical universe comprises an abundance of styles and genres across historical, artistic and musical boundaries, yet still constitutes an intellectual whole, a cohesive musical oeuvre that can rightfully be acknowledged as Modern. Modern not just in its everyday sense, but also ideologically, it contests tradition, resists norms, neutralises the morally good and functionally useful, and insists on staging the dialectic continuum between secrecy and scandal.1
