John Mayer is one of the biggest singer/songwriters in the world. After a showcase at SXSW, he released his online-only debut Room for Squares, which finally saw a physical release through Columbia Records, garnering him two GRAMMY® nominations and a win. His sophomore album Heavier Things would prove equally successful, notching him his first #1 single. By his third album Continuum, his sound incorporated more folk, blues, and soul, which would inform his following releases.
