In the great cause of critical integrity, let me state a conflict of interest right out of the gate: I am one of the producers of “Garland Jeffreys: The King of In Between.” All right, maybe not. I did, though, contribute to the film’s Kickstarter campaign in the amount of $25. A more princely sum was beyond my means, but Mr. Jeffreys’s music has been an integral part of my life and thanks had to be proffered, however humble.

The tagline for “The King of In Between” comes courtesy of an unnamed newscaster whose voice we hear during the film’s opening moments: “The name Garland Jeffreys either means nothing to you or everything to you.” Hyperbole is part-and-parcel of show business. Still, that’s not to say Mr. Jeffreys’s music hasn’t connected with audiences the world over. What those audiences may have lacked in size they made up for in loyalty and enthusiasm. And, of course, taste — but, again, I’m a fan.
