sun_records_promo_1I was the worst audience for the hit musical “Million Dollar Quartet” despite my love for the music, because I had serious issues with all its changed details about the rise of rock ’n’ roll in Memphis. But the spin-off TV series “Sun Records” (CMT, 10 p.m.) has plenty of time to sort out those details — and the guy to do it, music journalist Colin Escott, even as it includes some tasty musical bits in telling the tales of the rise of Elvis Presley, Johnny Cash and the stars of the fabled recording studio.

It seems like they got teenagers who play the main roles and I had problems with the casting of Chad Michael Murray as label founder Sam Phillips (blonde?). but he shows some credible passion for the music he records. Jerry Lee Lewis isn’t even in the mix yet, and B.B. King arrives next week. And while the marital infidelity subplot seems unnecessary, it seems like the series has a lot going for it.

It follows a key episode of the transplanted “Nashville” (CMT, 9 p.m.) in which the fate of Connie Britton’s Rayna James may be determined after a big accident last week. Together, it makes a night of music-oriented, Tennessee-centered drama on the network.

Famke Janssen takes up the role of Scottie Hargrave of a private military intelligence firm, introduced on “The Blacklist” (NBC, 9 p.m.) last season, for her own stand alone spin-off, “The Blacklist: Redemption” (NBC, 10 p.m.). As in the original show, she has a mysterious connection to the spy played by Ryan Eggold.
