Step-by-step explanation:
The genre that started out with black/latino DJs spinning records in public is Hip-Hop. This cultural movement gained prominence in the 1980s, emerging from inner cities and spreading to small towns. Hip-Hop originated from the streets where DJs combined elements of 1970s funk with their own beats and lyrics. Pioneering artists developed the art of rapping and used turntables to create their music, which was distinct from traditional musical accompaniment.
While other genres such as Jazz and Rock and Roll also had profound impacts on American culture and helped blur racial lines, it was Hip-Hop that was born from the urban experience voiced by black and Latino DJs. Hip-Hop has undergone various transformations over the years, with rappers from different regions adding their own local flavor, contributing to the genre's rich and diverse history.
