The musician was joined by Chad Smith and Questlove during the O Music Awards event.
Andrew W.K. has made it through 24 hours of drumming -- with a little help.
"WE DID IT!!! 24 HOURS OF DRUMMING!!!" the musician tweeted on Thursday night. "Remember... I didn't do it, WE did it. You were with me every beat. I feel very emotional and party."
Performing as part of the O Music Awards, he set out on Wednesday night to break break the record for the longest drum session in a retail store. His day-long session was held in Times Square and broadcast as part of the award show's live-stream.
Making it until the end wasn't easy: "My hands and back are hurting," he tweeted with over two hours still to go. "Oh JOY!" he added as he hit the final hour.
The rocker and motivational speaker was joined by drummers ranging from Red Hot Chili Peppers' Chad Smith to the Roots' Questlove.
"Some of these I would consider the greatest drummers in the world," W.K. said of his special guests before the event kicked off. "People that I've admired for years and years."
