Friday marks the 50th anniversary of hip-hop, a musical genre that has shaped the city and the world.

Its roots date back to 1973 in the Bronx when DJ Kool Herc reportedly mixed two copies of the same album into one backbeat.

From there, hip-hop grew bigger and more popular, and has even played a role in the push for social justice.

Lt. Gov. Antonio Delgado joined host Errol Louis on "Inside City Hall" Wednesday night to discuss hip-hop, the impact of the genre and his career in music.

"Understanding the origin story of hip-hop, knowing that it came from the margins, that it came from communities that were overlooked and underserved, that were desperate to be heard and desperate to be seen and no longer forgotten. And understanding that that in and of itself is political," Delgado said.

Delgado also talked about anti-hate groups and the influx of migrants arriving in the city.
