best artists in the last 15 years


I am wanting to focus on the newest and up coming artists. Specifically rock,folk and jazz or a mix of them. Who is most likely the most talented, best written and produced
arp
Diana Krall-Jazz..You've got to be kidding...Saw her car commercial mentioning being a jazz muscian.What a joke........What about her makes her a Jazz musician?JD
Arp, Gospel? Yes, Fairfield Four. I am sure others to boot, but this is a great album.
Hamid Drake: drummer. Student of the late Ed Blackwell. Plays with William Parker a lot. Has done records with Cecil Taylor, Bill Dixon, and Pharoah Sanders. Amazing.
I could list several, but because John Darnielle is underappreciated, I would point you all toward The Mountain Goats if you value great songwriting.
