Incorporating the warmth, melodies and simplicity of 70's and 80's California rock/pop, Battle Studies is a confessional, relaxed and liberated album recorded in a private home in California where Mayer lived and worked over the course of six months before wrapping at the famed Capitol Studios in Los Angeles.

The album's first single, "Who Says" challenges conventional standards of what one can accomplish or undertake - despite society's constraints. Battle Studies also showcases universal themes on "Heartbreak Warfare," "Assassin," and "War of My Life," while flexing guitar chops on "Rock Song," and a reinterpretation of "Crossroads." The famously collaborative guitar player also invited one of music's brightest new talents, Taylor Swift, to appear on "Half of My Heart."

"I approach music like a director doing a period piece," says Mayer. "Where Continuum was R&B and Soul, Battle Studies was written with the timelessness of Tom Petty, Fleetwood Mac and Neil Young in mind. The melodies and message are concise and from-the-gut with the efficiency of simplicity."
