Do you have a preferred artist or band that isn't widely recognized in the mainstream?

Umphreys, Lotus, and STS9 have always been kind of a trifecta for me. I've also always liked Papadosio and it feels like they're just getting better every time I see them.

Potentially less widely known, a Michigan band called Chirp. I also recently discovered Kendall Street Company and their interpretation of Eyes of the World is so good it haunts me.
