DJ Grandmaster Flash joined “In Focus” to take a look back on hip-hop’s evolution.

He’s considered being one of the pioneers of hi-hop DJing, cutting, scratching and mixing. Grandmaster Flash developed standard DJ innovations like the backspin, punch phrasing, and scratching.

He discussed growing up in the Bronx and explained when he first discovered his love for music.

In the late 70s, he formed the group Grandmaster Flash and The Three MCs. The group then became Grandmaster Flash and the Furious Five and is known for driving the birth of hip-hop in the South Bronx in the 1970s.

Grandmaster Flash reflected on how the group quickly gained recognition for their skillful raps and freestyle battles.

The influential tracks include “Freedom,” “Birthday Party,” and “It’s Nasty.”

Grandmaster Flash and the Furious Five became the first hip hop act to be inducted into the Rock & Roll Hall of Fame, and had the first hip hop recording added to the national recording registry.
