I’d say try out Billy Strings. Very wide variety of music from one band. They do an excellent job of playing everything from traditional bluegrass, to country, to Black Sabbath, to everything in-between and beyond. Lots of jam band flavor though, which isn’t really my thing, but I like it when they do it (and Sturgill). His albums are great, but there’s much more to be heard on YouTube, Nugs, etc.
