Following the US Supreme Court's ruling in the case against Arizona immigration law SB 1070, the Los Angeles Times' Pop & Hiss blog put together a list of "five great songs about immigration that are worth revisiting," including Ry Cooder's "Quicksand" along with songs by Rage Against the Machine, Bruce Springsteen, U2, Woody Guthrie, and Led Zeppelin. "For decades, Cooder has written blues-rock at the junction of L.A.'s Anglo and Latino cultures," says the LA Times. "'Quicksand' is one of his most vivid character sketches about a harrowing border crossing." Cooder wrote the song in response to the passing of SB 1070 in 2010 and donated the proceeds from its sale to MALDEF, the Mexican American Legal Defense and Education Fund.
