John Mayer Undergoes Throat Surgery

Grammy winner announces granuloma diagnosis after series of concert cancellations

Singer/guitarist John Mayer has enjoyed a long, Grammy-filled career thanks to his bluesy rasp. But after canceling a series of recent performances to rest his voice, Mayer announced that he had gone under the knife to correct a throat problem that had laid him low.

Mayer was diagnosed with granuloma (throat inflammation) just above his vocal cord last month and has been ordered to take complete vocal rest for at least a month after the surgery.

"I wanted to give you an update on the granuloma just above my vocal cord," Mayer wrote on his Tumblr. "I had surgery this afternoon to remove it and am now on complete vocal rest for a month or more. 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."

Mayer canceled some performances last month, including an appearance at the first-ever iHeartRadio Music Festival in Las Vegas as well as a show with Tony Bennett in Los Angeles. In addition, his upcoming fifth album, Born and Raised, which was originally slated for release this fall, has been pushed back to next year.

"I should be frustrated but I can't seem to stop thinking about beautiful things," Mayer continued. "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."
