DECADE follows the fascinating career of alternative singer/songwriter and cult favorite Melissa Ferrick through 10 turbulent years. Signing with and being dropped from a major record label, sobering up, going independent, and finally founding her own burgeoning Right On Records, Ferrick has managed to stay true to her own musical vision in a world that often discourages originality. This program serves as both an excellent introduction for the uninitiated and a treasure trove of information for “Ferrick Heads.”
