Neil Young and Crazy Horse perform "Down By the River" live at the Farm Aid concert in New Orleans, Louisiana on September 18, 1994. Farm Aid was started by Willie Nelson, Neil Young and John Mellencamp in 1985 to keep family farmers on the land and has worked since then to make sure everyone has access to good food from family farmers. Dave Matthews joined Farm Aid's board of directors in 2001.

They've raised their voices to help — what can you do
