There’s been a steady drumbeat of music-history documentaries this century, paying proper homage to the great players of pop music. These movies are invariably tuneful and nostalgic. Actually, there have been so many of these — “Standing in the Shadows of Motown,” “Muscle Shoals,” the recent Oscar winners “Searching for Sugar Man” and “Twenty Feet from Stardom” — that you might suspect the genre is a little played out.
But no. Even a wobbly offering like Take Me to the River contains irresistible moments of musical pleasure.
