New bands like the ones you listed? That's a pretty broad range, so I'll just list a few modern(ish) bands here that you may or may not already know of, but that I really enjoy personally.
Robert Randolph freaking slays the steel pedal guitar

Moon Taxi can sometimes get a little on the poppy side but sometimes they bring the funk and sometimes they bring the old school sound, and I've been really diggin them lately. Also, they have an awesome name.
