Not sure if this counts as "no one's ever heard of" because it was played as the intro song for The Walking Dead: The Final Season, which is one of my favorite games at the moment. It can be considered a country/indie song. I'll link one of their songs.
The song is called "Waiting Around To Die" by The Be Good Tanyas.
This band right here, saw them a week ago supporting the great SURFBORT. It was mental and even though its a big between LULA and SURFBORT soundwise, the energy that night from these two bands are still tickling my bones!
