My wife and I were big fans of Sons of Anarchy. As TV series go, it faded towards the finish line, but it still had its moments. It always incorporated some fantastic music in the background which greatly enhanced the show.
One song they used in 2014 was Yelawolf’s “Till It’s Gone”. I had never heard it, or of Yelawolf before. But it stuck like glue. Tense, longing, sad and pained in both sound and lyrics, it fit the episode and the show as a whole.
