Several of the original architects of Hip-Hop are coming together to celebrate “No Profanity Day” in New York City Friday. The special holiday was instituted when last week the New York State Assembly unanimously passed a resolution submitted by Assemblyman Ruben Diaz, Jr.on behalf of rap pioneer Minister Kurtis “Blow” Walker.

A bevy of Hip-Hop legends are expected to gather in the Bronx tomorrow, for a history-making concert - “The No Profanity Hip-Hop Anniversary Tour” - at Utopia’s Paradise Theater.

The three-hour curse-free concert will feature performances by the genre’s early icons, including the day’s leader Kurtis Blow, Afrika Bambaataa & the Soul Sonic Force, Grand Wizard Theodore, and Grandmaster Mele Mel.

Also billed to perform are Spoonie Gee, Rob Base, Dana Dane, DJ Hollywood, Positive K, the Force MDs, The Air Force Crew, Rew York, and Kurtis Blow, Jr.

“I’ve always been a stickler for being more conscious of the lyrics in Hip-Hop,” Kurtis Blow told AllHipHop.com. “Not only do I think it’s important to support no profanity in Hip-Hop and rap music, but also it’s more important to support no profanity in everyday life because in our society, most violence starts with the way we talk to each other.”

Kurtis Blow, who has recorded over 150 songs without any profanity, is also the co-founder of Harlem’s Hip-Hop Church.
