As others have said, check out Billy Strings. This young guy is phenomenal. He plays guitar, banjo, and mandolin; sings; and writes songs. Knows all the classic tunes, and seems to be all about the music. I just love him!
If you haven't seen it, this YouTube of him with Del McCoury is a great, It's hard to say who's more thrilled, the young guy playing with the legend, or the legend playing with the young guy sure to carry the torch forward.
