I've poked around at blues and old country and gospel but just haven't found anything I like as much. These songs are all covers, but compared to the originals they're stripped down, more sparse. Someone help me out in listening to something new for once? Spotify and YouTube's recommendation engine just points me to other video game soundtracks, not stuff that sounds similar.
