In a new interview with Rolling Stone, Robert Plant discussed a possible reunion with Alison Krauss for a follow-up to 2007’s Raising Sand. Plant, who is about to embark on a tour with his Sensational Space Shifters, said that Krauss called him recently about the possibility of a new album in the vein of Daft Punk.

“She keeps saying, ‘Now we’ve got to do it like Daft Punk,’” says Plant. “I said, ‘Alison, get a clue. We’ve got great voices. We need to be getting ourselves around some really pretty songs if we sing together.’ And Daft Punk? We can go out for dinner with Nile Rodgers, but that’s about it.”

As noted in the interview, this wouldn’t be the first reunion between the two Raising Sand singers. Following their tour in 2009, Plant went into the studio with producer Daniel Lanois to write material to sing with Krauss.

“We walked away from that and took our toys back,” says Plant. “Dan and I wrote about five songs in two or three days up in Silver Lake. They were pretty good, but they didn’t really lend themselves to a vocal collaboration, so I took them away.”

Plant’s new album, which currently remains untitled, is due to be released on September 9. “It’s really a celebratory record, but it’s very crunchy and gritty, very West African and very Massive Attack-y.”
