HIP-HOP legend Fatman Scoop was rushed to hospital on Friday night after collapsing on-stage mid-performance.
Disturbing footage appeared to show the star being given CPR after passing out behind a DJ booth - as panicked concertgoers screamed in confusion.
The hypeman, real name Issac Freeman, 53, was performing a set at the Town Center Park in Hamden, Connecticut when the frantic scenes unfolded.
After addressing the crowd at the front of the stage, a shirtless Freeman walked behind the DJ booth and collapsed, video obtained by shows.
Another performer stopped the music and continued to talk to the crowd as emergency responders rushed over and starting giving him chest compressions.
Desperate fans could be heard screaming at the performers, asking if Freeman was okay.
"Nothing going on - on the stage. I just want to say this - Hamden, where y'all at, make some noise for me heavy baby," another performer was heard telling the crowd in the video.
Onlookers were heard saying "Oh my god!" and "We want to know what happened to Fatman."
"Is he alright?!" another screamed.
Blurry footage also showed Freeman on a gurney outside of the venue as first responders crowded around him.
They continued to perform chest compressions outside as one fan was heard saying, "Lord touch him - please Father, God touch him."
First responders arrived at the concert and took him to a nearby hospital.
Hamden's mayor, Lauren Garrett confirmed on that Freeman was the performer who received the chest compressions.
She announced that Freeman had a "medical emergency" and was taken to the hospital in an ambulance.
"Please keep him in your thoughts and prayers," she added.
The U.S. Sun has reached out to Freeman's team and the Hamden Police for more information.
