Unfortunately even your "newer bands" are 10-15+ years old.
I do like some of the bands you've mentioned here, as I'm a big alternative music fan. So Broken Bells, Joywave, etc are solid bands.
Young the Giant
Band of Horses
Head and the Heart
As far as what I'd consider "new," as in the last 2-3 years? Check out Odesza, Tame Impala, Lord Huron, the 1975, Sam Fender, Glass Animals.
I'm in my 50's, so I could write a book on what I think is wrong with music, and some of these newer groups and artists are proof positive that we're kinda in this black hole of EDM adjacent light generic pop music.
There really isn't rock in the sense we know it. Dangerous, rebellious, anti-authority, loud, obnoxious, brash, even offensive. That doesn't exist. None of the 4-5 giant conglomerates that control all of radio now would allow that. They want safe.
