Singer/songwriter John Mayer has undergone throat surgery to remove a granuloma from just above his vocal cord.
The Daughters and Waiting For The World To Change hitmaker made the announcement on his blog, revealing he is now "on complete vocal rest for a month or more".
He writes, "It's been a very long process in waiting to see if time was an alternative to surgery, but even given two weeks' voice rest (along with many other approaches), there was no change for the better."
He adds, "I should be frustrated but I can't seem to stop thinking about beautiful things... I never thought I'd be wishing I could do what I love again; I stay in at night, picking guitar parts off of records and dreaming of playing on the big stage. The only difference between now and when I was 18 is that now I have this beautiful, meaningful record waiting for me when I can sing it.
"Until then, I'm taking off. Going to travel the country, look and listen."
