Well a good majority of us saw and heard Adele sing Sunday night at the Grammy awards.. yes she sounded amazing, but did you notice the difference in her voice? Adele says that as a result of the surgery and having the polyp removed, her voice changed and went up and octave. She says that she's ok with it cause she still sounds like herself, she was just surprised it went up and not deeper.
By the way.. Adele is working on a third album!
