Say what you will about freak-folk's tendency toward suffocating pastoralism and idealized naivete, but it's breathed second life into some very worthy '70s curios. Like Vashti Bunyan's debut and The Valerie Project, Gary Higgins' lone LP — 1973's long-forgotten folk gem Red Hash — truly deserved its spin in the cultural recycling machine. Banner wavers like Devendra Banhart and Ben Chasny fell under its melancholic spell, and Drag City re-released it in 2005. Today, presented free by the Department of Cultural Affairs and Pitchfork, Higgins' psych-tinged languor makes for a perfect Monday picnic soundtrack. Chipotle will still be there tomorrow; spend this lunch in the park with a lost-and-found folk hero.
