I’ve never looked through Chicago Blues, a book of blues photographs shot in Chicago by Raeburn Flerlage (who died in 2002 at age 87) and published in 2000. But after spending some time with a new volume of his gorgeous black-and-white photography I realized that I’ve seen plenty of his work without knowing it. Back in the 60s he shot album photos for labels like Chess, Delmark, Testament, Folkways, and Prestige. And the terrific new book Chicago Folk: Images of the Sixties Music Scene (ECW Press) collects his photographs of the folk-music revival, particularly of concerts at the University of Chicago Folk Festival during the 60s.
