Steely Dan played at Coachella this year, and Donald Fagen kept a journal throughout their stay. I haven't read all of it yet, but there was a piece on Stereogum titled After Coachella, Steely Dan's Donald Fagen Not Psyched About Modern Music. I skimmed over the entire entry on Rolling Stone and he said he's been "hearing this stuff for nearly half a century and it's getting pretty dreary." This "stuff" is "c. 1965 Dylanesque mode, minus genius or anything like that."
Genius is both objective and subjective. I think Jackson Browne is a genius. I think Dawes is a brilliant band. I describe Dawes to someone unfamiliar with them by saying imagine Jackson Browne as a band, and you get Dawes. Is Dawes or Jackson Browne completely original? No, and they'll tell you that. As for the dreariness that Donald Fagen speaks of, I can see where he's coming from. He admitted that at one point he, too, was doing Dylanesque stuff. How can anyone who calls himself a songwriter not pass through Bob Dylan?
Will the remainder of the bill at Coachella grow into their own? Sure. Some already have. Will they meet Donald Fagen's or any of the titans of rock standards? Not likely. I say that tongue-in-cheek. I love those titans of rock.
Anyway. I guess what I'm saying is, you can't please everybody, and you're not perfect out of the gate.
