Seven-time Grammy Award-winning singer and musician John Mayer launches his first U.S. tour in two years on April 9, with 18 concerts that will raise money to benefit US veterans. The tour leads into Mayer's upcoming fifth album Born and Raised, which will be released in May.

Mayer became passionate about supporting U.S. war veterans following a visit to the Marine Corps' Camp Lejeune in North Carolina four years ago. He has since spent time with active military and veterans while touring, and partnered with the Northern California Institute of Research and Education (NCIRE) to provide veterans with a healthy reintegration into civilian life, helping to heal the battle scars caused by the trauma of war.

Concertgoers can join Mayer in his support of veterans in two ways. A block of third-row orchestra seats will be made available for sale at a premium price exclusively through Tickets-For-Charity, with proceeds going to Mayer/NCIRE programs. At Tickets-For-Charity, fans pay the same or better price found elsewhere for high-demand seats, with 100% of above-face benefit redirected to charity. Many of these tickets have already sold-out: www.ticketsforcharity.com/johnmayer.

And at Celebrity.ebay.com/john-mayer, Mayer fans can bid on four front-row tickets, plus a chance to meet him, with proceeds also going to Mayer/NCIRE programs for veterans.

Mayer's previous albums–Room for Squares, Heavier Things, Continuum and Battle Studies–have sold more than 11 million copies combined. Besides his seven Grammy Awards an additional 11 nominations, he has also been included in Time Magazine's annual Time 100 list of the most influential contemporary thinkers, leaders, artists and entertainers, and twice been featured on the cover of Rolling Stone Magazine's annual "Guitar" issue.
