“Anatomy of a `Homicide’ “: If the process of television is as interesting to you as what ends up on the screen, don’t miss this two-hour program (10 p.m., WYCC-Ch. 20) about the making of one of series television’s very finest hours. Filmmaker Ted Bogosian caught NBC’s “Homicide: Life on the Street” in the midst of crafting its acclaimed “The Subway” episode. Centered on a conversation between the show’s Det. Pembleton (Andre Braugher) and a commuter (Vincent D’Onofrio) fatally pinned between subway car and platform, “The Subway” is a horrifying, eloquent and haunting hour, and it runs in its entirety as the second half of the insightful “Anatomy” program (which first aired on PBS last November). Elsewhere tonight, the great Lucinda Williams and the sometimes-great Vic Chesnutt are spotlighted in the improving PBS performance series “Sessions at West 54th” (12 a.m., WTTW-Ch. 11). If you happened to catch its hour last week with Steve Earle and Del McCoury’s bluegrass band, you saw something very special. One extramusical highlight came from Earle, who said that “one of the main reasons that country radio (is so bad) nowadays is that they’re afraid to play songs about killing people.”
