Robert Plant enjoys singing with Alison Krauss, but stresses they're not like some of the male and female duos that were prominent in the '60s and '70s.
He tells the Los Angeles Times, "We’re not Dale & Grace or Sonny & Cher, but we’ve definitely got something going on. We’ve got two totally different lives running. Alison’s a lot more private than I am. I’m out in the flood. I’ve lived where I’ve always lived.
As for how they approach singing together, he tells Rolling Stone, "We kind of watch each other when we’re singing, and you can more or less tell. I’m still slightly impish, so I might hold one syllable of a word a little bit long, and she hangs on with me, and she doesn’t know when it’s going to end, that particular syllable. So if you are able to watch, the eyebrows tell everything, like she’s asking me, 'Why am I doing this? Why are you [screwing] about like this?' It’s great. And so I have this license where I can actually get away with it, and I’m singing alongside a monster singer who has great demands of how my harmony fits under the songs that she selected."
Robert and Alison are currently on tour in support of their second album, 2021's Raise the Roof. Up next are shows in Sandy, Utah tonight; Morrison, Colorado on Thursday; Grand Prairie, Texas Saturday; and Austin on Sunday. The tour ends September 12th in New York City.
