Band of Joy guitarist and producer Buddy Miller has revealed that Robert Plant visited his home studio in Nashville last year for a joint songwriting session in which the pair ended up recording with Band of Joy drummer Marco Giovino.

"We didn't mean to, but we sort of wrote a record's worth [of material] and I said, 'While we're doing this, why don't I put up some mics and document it,' because that's better than just trying to remember it or record it on your phone," Miller explains. "And it sounded so good I think we, you know, accidentally made a record."

"I don't know how much [Robert] would want me talkin' about it," Miller continues. "If the last record might be pastoral, parts of it, [this one's] much more tribal; it's much more urgent and tribal and, dare I say, rockin'!"

"He's Robert Plant and he can do whatever he wants to," Miller adds. "He's got some Zeppelin stuff coming up now, so it's going to be next year before [the record] sees the light of day, that's what we're talking about."
