CNN: First of all, this is the screwiest collaboration I had ever heard of. Plant: When she goes up for these wailing notes on stage, that's where I want her to go with this new project -- occasionally visit these places where she lets rip, and just lets it really come out. Krauss (melodramatically): It's just reckless abandon! Following the end of that relationship in 2013, he returned full-time to Worcestershire, England, not far from the Welsh border.Back in England, he revitalized his former band, Strange Sensation, and christened the new group the Space Shifters.
Once upon a time, the iconic lead singer of Led Zeppelin and the golden girl of bluegrass would never have been mentioned in the same sentence. I haven't even gotten off to being bullied enough yet. And also, I didn't understand the history of where Alison's from [bluegrass], and has been since she was a child. So we've got lots in common -- but it's the presentation and the whole musicality of it that's different.
