Adele explains technical difficulties at Grammys

Adele says technical difficulties were to blame for her unusual off-key performance at the Grammy Awards on Monday night (15Feb16).

The British soul star was one of the most anticipated performers at the Los Angeles prizegiving, but when she took to the stage to perform her 25 track All I Ask, it was marred by sound issues from the get-go.

The sound cut out on the live broadcast for a few seconds early into her set, and throughout the rest of the performance, fans and critics alike were quick to point out Adele didn't sound like herself.

At the end, the multiple-Grammy winner looked a little exasperated, with her fans calling for the ceremony's sound engineer to be fired in a series of social media rants.

Later that night, Adele took to Twitter.com to explain what went wrong, writing, "The piano mics fell on to the piano strings, that's what the guitar sound was. It made it sound out of tune..."

But Adele didn't let the performance ruin her night, adding, "Because of it though... I'm treating myself to an (popular California fast food restaurant). in n out. So maybe it was worth it."

A spokesperson at network CBS, which aired the telecast, confirmed to Billboard that there was a five-to-eight second technical issue with the broadcast, and that it was outside the network's control.
