Before starting his multi-platinum solo career, he was a founding member of the folk-rock band Buffalo Springfield and worked with the groups Crazy Horse and Crosby, Stills and Nash. The Canadian singer-songwriter was recognized by the Rock and Roll Hall of Fame in 1995 for his work as a solo artist and was inducted into the Canadian Music Hall of Fame in 1982. Young's philanthropic work is as renowned as his musical legacy. His famous Bridge School Benefit Concert has become a yearly tradition since 1986 and continues to boast an incredible line-up of high-profile artists. Each year, Young donates all of the proceeds to the Bay Area's Bridge School, which assists children with severe physical impairments and complex communication needs. He was also one of the original founders of Farm Aid in 1985, and continues to be an active member on the organization's board of directors.
