In the Bronx, street parties started sprouting
up on a regular basis. In addition to Dj Kool Herc, the other
main Djs in this burgeoning Bronx party scene were Afrika
Bambaataa and Grandmaster Flash. During these years, Herc,
Bambaataa and Flash performed at house parties, street parties,
and public parks, flooding the neighborhoods of the Bronx
(particularly South) with dance music.

As a child, Grandmaster Flash was fascinated with music and
often played with his father's record collection, despite
being told to stay away from it. He also loved all things
electrical, and would often take apart whatever household
appliance he could get his hands on. While studying to be
an electrical technician, he saw Dj Kool Herc spin at a party.
Inspired, Flash gave up his studies and devoted himself full-time
to the wheels of steel, effectively combining hi two passions.
A true innovator, his turntable skills are legendary.
DJ Cool Herc and Coke La Rock

Dated December 1976, this flyer advertises an early hip-hop
show by DJ Kool Herc and Coke La Rock. Drawn on light pink
paper, it features handwritten text and a freehand sketch
of two dancing figures. Presented by the Teen Council, this
Disco Smoker (as the event was described) was held
at the Webster P.A.L. (Police Athletic League) in the Bronx.
This rare handbill is one of the earliest hip-hop posters
in Hip-Hop's: Now and Then collection.
Zulu Nation Graffiti Artwork

After seeing Dj Kool Herc perform around the neighborhood,
gang leader and social activist Afrika Bambaataa got his won
equipment and started throwing parties, eventually forming
the Zulu Nation, a collective of Djs, breakers and graffiti
artists. Bambaataa brought a political and social consciousness
to hip-hop, and under his influence, ghetto youth begin to
turn away from violence and toward music. The Cold Crush Brothers
created the original artwork, and Dj Tony Tone, who at the
time used the tag "Chain 2".
Grand Wizard Theodore

Grand Wizard Theodore - the younger brother of Grandmaster
Flash's early partner, Dj Mean Gene - is credited with inventing
scratching. Though Mean Gene forbade his younger brother to
touch his equipment, Theodore would sneak into his room and
fool around with the turntables while his other brother was
at work. It was during one such episode that he invented scratching.
