John Mayer Cancels Shows, Delays Album Due to Throat Problem.

John Mayer is canceling two upcoming performances and postponing the release of his next album due to a vocal cord issue.

He announced the news on his blog.

“After several months of going week to week monitoring and hoping to correct the condition, I am forced to cancel my upcoming singing engagements due to something next to my vocal cords called a granuloma,” he explains.

Mayer doesn’t go into the specific nature of his granuloma, which is broadly characterized as a tissue inflammation.

He’s dropped out of next weekend’s iHeartRadio Music Festival in Las Vegas, as well as an upcoming performance with Tony Bennett in Los Angeles.
