John Mayer cancels concert tour

John Mayer says he axed his planned U.S. concert tour and will take an indefinite hiatus from live performing due to the return of the granuloma in his throat. Columbia Records said the singer, songwriter and musician was treated for the same condition and placed on extensive vocal rest last year. The recently announced tour was to be his first in the United States in two years. His new album \"Born and Raised\" will be released as planned by Columbia Records May 22, the label said. \"Somewhere in all of this is another surgery and a very long chemically-imposed period of silence, so I hope you\'ll understand that I have to really pick that date [on which I return] carefully. I\'m pretty emotionally burnt out at the moment, but please know how hard I tried to resolve this and how disappointed I am that I can\'t perform this record yet. I\'m completely bummed, especially for all of you who started making plans to see a show,\" Mayer wrote to fans via his tumblr blog Friday. \"Nothing feels worse than having to break the stage down before the performance, and I mean nothing. I love this band you were going to hear, I love the guys and girls I work with, and the only thing that stops me from devolving into a puddle of tears is knowing that it\'s a long life, and the greatest gift in the world is being able to create music no matter what the circumstances.\" Ticket purchasers should refer to their point of purchase for refund details.
