Afrika Bambaataa & The Soul Sonic Force - Planet Rock (1982)

"Planet Rock" is a 1982 song by Afrika Bambaataa & the Soul Sonic Force. Although it was only a minor hit in the US, Canada, and the UK, it helped change the foundations of hip hop and dance music. It is credited with re-developing the electro style that was originally pioneered by Kraftwerk and helped pave the way for other genres such as electro, house, and trance. November 2004, the "Planet Rock" placed at #237 on  Rolling Stone Magazines 500 Greatest Songs Of all Time and #10 in About.ComsTop 100 Rap Songs. "Planet Rock" peaked at number four on the soul chart and number forty-eight on the Hot 100, and went to number three on the dance charts.
Produced by Arthur Baker, "Planet Rock" blends synthesizer and vocorder sounds with breakbeats. It was influenced by artists such as Kraftwerk, Gary Numan, and George Clinton.. It was the first hip-hop recording to use a drum machine.
The record was recorded in the NYC upper eastside Intergalactic Studios, a popular site for NYC clubscene productions. Toward the end of the scheduled recording session, NYC music clubscene fixtures DJ David Azarc, soundman Jim Toth, and promoter Tom Goodkind—all from the Peppermint Lounge—asked Arthur to please hurry. The three had scheduled the next recording session for a band that would become the Washington Squares. Ever accommodating, Arthur told them that things would move faster if they assisted him with the backup vocals. The voices singing "rock it don't stop it" on Planet Rock are in fact those of the Washington Squares.

The influence of "Planet Rock" can still be heard in hip-hop sub-genres such G-funk and in the work of producers such as the Neptunes, which use electro-based sounds in its productions.
In 2008, it was ranked number 21 on VH1's 100 Greatest Songs of Hip Hop.
