At the heart of Phil Ochs' affecting folk tunes is a strong sense of social justice, and the protest songs made in his wake each owe a little to the ‘60s singer. They can be be incensed and filled with vitriol, like Bright Eyes' bare-bones George W. Bush put-down “When the President Talks to God,” or quiet and thoughtful, like Springsteen's spectral “The Ghost of Tom Joad,” but they're always imbued with Ochs' unwavering support for the underdog.
