Eidolonios
Check out Dugas. Christian and Sarah have been going at their own project since The Duhks. As far as I know Scott's back with them again. They're friends of mine, but I moved to Edmonton so it's been a while since I've seen any of them :3
Oh, and you'd probably like the Bros Landreth, too.
I checked out some songs on youtube and I really like Sarah's voice. I wish I could belt out notes like her, it's crazy! I really like this genre because there's so much soul behind the music and it has a rustic quality; unlike all the auto-tune pop music. Thanks for the suggestions!
