John Mayer (John Clayton Mayer) was born on October 16, 1977 is an American singer-songwriter and guitarist. Originally from Connecticut, he briefly attended Berklee College of Music, before moving to Atlanta, Georgia in 1998, where he refined his skills and began gaining a following.

His first two studio albums, Room for Squares and Heavier Things, did well commercially, achieving multi-platinum status.

In 2003, he won a Best Male Pop Vocal Performance Grammy for "Your Body Is a Wonderland".

Mayer began his career performing mainly acoustic rock, but gradually made a transition towards the blues genre in 2005 (including collaborations with renowned blues artists such as BB King) and formed the John Mayer Trio.

The blues influence can be seen on his album Continuum, released in September 2006. Mayer won Best Pop Vocal Album for Continuum and Best Male Pop Vocal Performance for "Waiting on the World to Change" at the 49th Annual Grammy Awards in 2007.

Mayer's career pursuits have extended to stand-up comedy, design, and writing; he has written pieces for magazines, most notably for Esquire. He is also involved in philanthropic activities through his "Back to You" fund and his efforts in reversing global warming.
