Since undergoing vocal cord surgery last October, John Mayer has slowly returned to promotion for his upcoming album Born and Raised, releasing first single "Shadow Days" last week in anticipation of a spring tour. Despite taking necessary precautions and committing to vocal rest following surgery, Mayer has experienced the regrowth of the granuloma that was originally operated on, a physical setback that will sideline him from live performances for the immediate future. The singer-songwriter explained the current state of his vocal health on his—new?—Tumblr:
During rehearsal on Tuesday, it came to mind that I should see my throat doctor because something didn’t feel/sound right. I went in for a visit on Wednesday and a scope of my vocal cords revealed that the granuloma has grown back where it had mostly healed. This is bad news. Because of this, I have no choice but to take an indefinite break from live performing. Though there will be a day when all of this will be behind me, it will sideline me for a longer period of time than I care to have you count down.
Mayer was scheduled to begin his tour on March 15 in Oklahoma City, hitting 18 cities through May, including a stop at the annual Jazzfest in New Orleans in late April. "I’m completely bummed, especially for all of you who started making plans to see a show. Nothing feels worse than having to break the stage down before the performance, and I mean nothing," he added. Fans who have already purchased tickets can get further information here. As of now, his fifth solo studio album will be released May 22 as planned, but without preceding live promotion. Best wishes for a speedy recovery.
