Robert Plant is highly amused by Paul McCartney’s dubbing the Rolling Stones “a blues cover band,” perhaps in part because his own old band faced similar criticism. “I don’t think there’s

any fighting,” he says in the new episode of Rolling Stone Music Now. “They’ve known each other since 1963. They love each other desperately.” Still, if there’s any animus, he knows how to

resolve it: McCartney, he says, “should just play bass with the Stones.” The singer was joined on this episode by Alison Krauss, who just recorded the excellent new album _Raising the Roof_

with him. Here are some highlights. To hear the entire episode, press play above, or listen on Apple Podcasts or Spotify.  PLANT GENTLY MOCKS ERIC CLAPTON’S VACCINE CRITICISM. “Good old

part that wasn’t fun was that he’s singing so off the cuff all the time,” she says. “It’s hard to harmonize if someone’s constantly in that state, which is magical if you’re _not_ trying to

harmonize, but if I’m trying to harmonize with it, it didn’t make it easy.” KRAUSS HAS FOND MEMORIES OF THE SUCCESS OF _O BROTHER, WHERE ART THOU?_ AND ITS SOUNDTRACK. “It showcased

bluegrass music in such a beautiful way,” she says. “It was a really emotional thing.” She only really learned just how big a phenomenon it was when she shared a bill with veteran singer

Norman Blake, on a tour sparked by the soundtrack. “He went out there to sing ‘Big Rock Candy Mountain,’ and the arena screams that came from him starting the show like that? I was blown

away.” EDITOR’S PICKS PLANT IS MOSTLY PROUD OF THE UPS AND DOWNS OF HIS POST-ZEPPELIN CAREER. “I was always trying to escape the shadow of what had happened to me between 1968 and 1980,” he

says. “So I was trying so many different things just to expand myself without really worrying about taking along an audience that only wanted me to be on autopilot. I made good music and I

made questionable music, but I did it all with great flurry. And there’s only a minor embarrassment now, maybe perhaps a few dodgy haircuts. I mean, when you’re on maximum rotation on MTV,

it’s just, how the hell did that happen? From the hammer of the gods to, um, [1983 solo ballad] ‘Big Log.'” PLANT SAYS IT WASN’T EASY SINGING THE HIGH NOTES IN ZEPPELIN — AND THAT THE

KEYS OF THE SONGS WERE BASED AROUND JIMMY PAGE’S GUITAR PLAYING, NOT HIS VOCAL RANGE. “Quite often everything was in E because you got much more out of the bottom of the guitar,” he says. “I

should have gone to one of those castrati schools in Northern Italy trying to get it right.” THE DUO — WHO LAST RELEASED _RAISING SAND _IN 2007 — WOULD LIKE TO KEEP THE COLLABORATION GOING

THIS TIME. “We’ve still got about 6,000 songs,” says Plant. “So if it feels good and there’s nothing to stop the flow, once we get on tour, maybe we pull up in some little town somewhere and

set up and record.” Download and subscribe to our weekly podcast, _Rolling Stone_ Music Now, hosted by Brian Hiatt, on Apple Podcasts or Spotify (or wherever you get your podcasts), and
