Andrew McMahon, frontman of rock outfit Jack's Mannequin [ tickets ], has been comfortable behind a piano for a couple decades now. He got his musical start at age nine with piano solos and formed his first band in high school, the members of which would later go on to join him in the pop-punk group Something Corporate. When McMahon noticed some of songs wouldn't fit with his band's sound, he decided to pursue it as a side project, forming Jack's Mannequin in 2004.

Just before the release of the piano-pop quartet's debut album, "Everything in Transit," McMahon was diagnosed with acute lymphoblastic leukemia. He fought the cancer and made a full recovery by mid-2006.

Jack's Mannequin is currently touring in support of their sophomore effort entitled "The Glass Passenger."
