The JB's, also known as James Brown's band, were a pivotal American funk group in the 1970s. Notable for their tight, propulsive rhythms and brass-heavy sound, they helped define the genre's instrumental style. They are most recognized for their work with James Brown, particularly on landmark tracks like "Get Up (I Feel Like Being a) Sex Machine" and "The Payback". Members, including Bootsy Collins and Fred Wesley, have had profound influences on the development of funk and soul music.
