After a bout with throat granuloma, John Mayer has announced his first tour in three years today. The singer will go on tour to promote his last album, Born and Raised, which came out in May 2012. The tour will see Mayer perform in over forty cities and travel across four countries.

Prior to the tour, Mayer will perform a gig at the Tuscaloosa Amphitheater on April 25, an already sold-out show. The following day, the singer will perform at the New Orleans Jazz & Heritage Festival.

Mayer is also this week's cover feature on Billboard magazine, where he spoke on the recovery process for his throat condition. It has been a rough road for Mayer, who had surgery in an attempt to rectify the granuloma; the surgery was unfortunately unsuccessful. An excerpt of the feature is available here.
