SEASON FOUR

Born and raised in Torrance, Calif., Danny Hamilton was hit head-on by a truck at age 14 and told that he may never walk again. Stuck in a wheelchair, he picked up a guitar and taught himself to play. He attended his eighth-grade graduation in that wheelchair, and showed up on the first day of high school walking on his own only three months later. There he discovered classic rock and soon started writing his own music. His bluegrass tinged roots rock and country sound has garnered Danny nominations for male singer-songwriter of the year awards at the 2002 and 2005 Los Angeles Music Awards. Find out more and watch his video "Bury the Devil."
