Adele performs onstage during The 58th Grammy Awards at Staples Center on Feb. 15, 2016 in Los Angeles, Calif.  

Adele took to the Grammys stage Monday night to perform her 25 track "All I Ask" -- and at least with Twitter as the barometer, the live rendition was not her best. Sound cut out on the broadcast for a few seconds early in the performance, and throughout, the singer didn't quite sound like herself.

CBS has responded to frustrated fans, with a spokesperson confirming to Billboard that there was a five-to-eight second technical issue with the broadcast, adding that it was outside the network's control. It appeared that the singer was singing without an earpiece, and that Columbia executives in the audience were visibly upset by the performance.

Billboard has reached out to Adele's representatives for comment. Adele herself tweeted after the show, "The piano mics fell on to the piano strings, that's what the guitar sound was. It made it sound out of tune. Sh-- happens. X."

"We have the most complicated technical show on television when it comes to music, bar none. Inside the piano are microphones, and a mike dropped into the strings. It happens to all sorts of people, but it rarely happens on our show," Recording Academy President Neil Portnow told L.A. Times. "When we switched over to the backup system, it had to drop out for a few seconds. When performing in intimate performance, it can be unnerving. We certainly don’t like it when those things happen, but they happen."
