The Upsetters were a Jamaican reggae and dub band, formed by legendary producer Lee "Scratch" Perry in the late 1960s. Their music is distinguished by a unique blend of reggae rhythms, experimental dubbing techniques, and Perry's idiosyncratic production style. Notable for their collaborations with Bob Marley and the Wailers, the Upsetters were instrumental in the development and global spread of reggae and dub music. Their influential works include the groundbreaking album "Super Ape" and the hit song "Return of Django".
