Drinks were flowing, the music was popping, and people were dancing Thursday evening in Oak Bluffs. Centric television, a cable channel owned by BET (Black Entertainment Television), threw a party at Hooked to celebrate its fourth year in business.

Outside the restaurant, guests formed lines to get in. Beyond the bouncers, photographers snapped shots of elegantly dressed guests while others lounged on couches beneath the stars. Inside, a mix of 90s and more modern hip hop set the beat for dancing.

Midway through the evening, hip-hop icons Doug E. Fresh and Slick Rick took the stage to the cheers of surprised partygoers.

The two performers, who became famous as individuals, worked together early in their careers. Known as the Get Fresh Crew, the two recorded “The Show,” and “La Di Da Di,” songs now considered two of the greatest early hip hop classics.

Before their performance, network executives announced a new late night show to be aired in the fall. The show, titled “Don’t Sleep,” will be hosted by T.J. Holmes, a former anchor and correspondent for CNN.

“In the new, original series ‘Don’t Sleep,’ Holmes will deliver smart, biting social commentary on significant issues important to African-Americans,” according to a press release.

Mr. Holmes attended Thursday’s event and asked attendees to tune in and tell their friends.

Hennessey, which provided guests with complimentary sweet and tangy drinks, was a host of the party.
