Boombox is a common term for a portable transistorized cassette tape recorder/player and AM/FM radio (and, beginning in the 1990s, a CD player) with an amplifier, two or more loudspeakers and a carrying handle. A boombox is a device typically capable of receiving radio stations and playing recorded music (usually cassettes or CDs, usually at a high volume). Many models are also capable of recording onto cassette tapes from radio and other sources. Designed for portability, boomboxes can be powered by batteries as well as by line current. The boombox was introduced to the American market during the mid-1970s. The desire for louder and heavier bass led to bigger and heavier boxes; by the 1980s, some boomboxes had reached the size of a suitcase. Most boomboxes were battery-operated, leading to extremely heavy, bulky boxes.
The boombox quickly became associated with urban society, particularly Black and Hispanic youth. The wide use of boomboxes in urban communities led to the boombox being coined a “ghetto blaster”, a pejorative nickname which was soon used as part of a backlash against the boombox and hip hop culture. Cities began banning boomboxes from public places, and they became less acceptable on city streets as time progressed. The boombox became closely linked to hip hop culture and was instrumental in the rise of hip hop music.

John Oswald described the art: “A phonograph in the hands of a ‘hiphop/scratch’ artist who plays a record like an electronic washboard with a phonographic needle as a plectrum, produces sounds which are unique and not reproduced—the record player becomes a musical instrument.”
Some turntablists use turntable techniques like beat mixing/matching, scratching, and beat juggling. Some turntablists seek to have themselves recognized as traditional musicians capable of interacting and improvising with other performers.
