1) “Country Music,” 8 p.m., PBS, rerunning at 10. Over eight nights and 16-plus hours, Ken Burns’ brilliant documentary will watch country music transform, while scrambling to keep its roots. The later chapters will include lots of first-person stories and TV clips; this opener, however, settles for old photos, second-hand accounts and great narration. In 1927, a New York producer set up recording sessions in Bristol, Tenn; Jimmie Rodgers (shown here)and the Carter family came, giving country a great start.
2) “Celebrity Family Feud,” 8-9 p.m., ABC. First, a rerun pits the married duo of John Legend and Chrissy Teigen against Lisa Vanderpump and her “Vanderpump Rules” cast. Then a new game has the families of Olympic medalist Ryan Lochte and “Tonight” bandleader Kevin Eubanks.
3) “NCIS: Los Angeles,” 9 p.m., CBS. It was 16 years ago that one of TV’s longest-running dramas spun into another: “JAG,” which ran a decade, begat “NCIS,” which has its own spin-offs. Now, “JAG” star David James Elliott is finally showing up in one of them; he’s still playing Harmon Rabb, now a Navy captain. Rabb links with Callen and Sam to find ISIS sympathizers targeting military locations. That srory continues in next week’s rerun … and in the season-opener, a week later.
4) Alec Baldwin roast, 10 p.m., Comedy Cenral. Roasts can range from sharp wit to dull crudities. A sampling – centering on one of the roasters, Caitlin Jenner – leans to the just-crude side. But Blake Griffin (a basketball star who dated Jenner’s daughter Kendall) has a witty line. Maybe there are more.
5) “On Becoming a God in Central Florida,” 10 p.m.,. Showtime. After wallowing in hopelessness for way too long, Krystal (Kirsten Dunst) finally finds some possibilities … albeit at other people’s expense. Widowed and swamped with pyramid-scheme debt, she turned to a “splashercize” class. Now the darkness descends anew, followed by fresh hope. Much of this centers on her boss (played by the terrific Mel Rodriguez), in a story that’s tough, but well-crafted.
