disc jockeys

People who select and play pre-recorded music for an audience, or an event. Originally, the term specifically referred to radio or television announcers that played, selected, and announced phonograph records. From the late 20th century, the practice of DJing has expanded to include the live manipulation of recordings using a variety of techniques such as "mixing" and "scratching". DJing has also become an accepted art form as it pertains to sound manipulation.
