The Upsetter tells the fascinating story of Lee Scratch Perry a visionary musician and artist from poor rural Jamaica who journeyed to the big city of Kingston in the late 1950's with dreams of making it in the burgeoning record industry. He burst upon the scene with a brand new sound, inventing a genre of music that would come to be called Reggae, discovering a young Bob Marley and gaining international recognition as a record producer and solo artist. Soon he was being called upon by artists as diverse as The Clash and Paul McCartney to provide his unique sound.
