The Grammy committee usually loves comeback stories. Whether it's artists who left the spotlight for a while and then returned with a vengeance ( Bonnie Raitt , Natalie Cole , Tina Turner ), veterans who reinvented their careers by collaborating with other musicians ( Carlos Santana , Herbie Hancock , Robert Plant ), or artists who struggled with their demons and made great music as a result ( Dixie Chicks , Amy Winehouse ), such rising-from-ashes back stories usually strongly resonate with industry voters.
