The album has 26 tracks and it looks like Sony posted videos of all the tracks here: https://youtu.be/1sfzoRw3ki8A limited series chronicling country music’s king and queen, George Jones and Tammy Wynette, whose wild and troubled love story inspired some of the most iconic music of all time.
I won't comment on the singing because, in my opinion, the actor and actress are given an impossible task, emulate George Jones and Tammy Wynette. But to my ears the audio production itself sounds as good as it gets.
Any idea who are the musicians and producers behind the music? Anyone know where the tracks were recorded?
