He was referring to sessions on the follow up to their Grammy winning album, Raising Sand. Plant went on to record Band of Joy instead of continuing with the Krauss collaboration. Alison Krauss returned to her band, Union Station, and recorded their sixth studio album.
In a piece in Rolling Stone this week, Krauss agreed with Plant that the sound wasn’t there. However, she wants to be clear that’s not the fault of the musicians they were working with:
I don’t want to make it sound like we’re saying that someone else’s performance wasn’t there - the band was fantastic, the same as the first record.
They traded compliments in their Rolling Stone stories as well, Plant saying:
Alison’s the best. She’s one of my favourite people.
Krauss is more backhanded in her return compliment:
He’s a delightful person, and I’ll never meet another like him.
Krauss’ new album, Paper Airplane is available April 12th. It is their first album since 2004’s Lonely Runs Both Ways.
