The band started touring in 2011 following an eight-year break, with Chela Rhea Harper on bass duties after Peulen originally refused to come back. Once they decided to record latest album Rivals - their first in 13 years - Peulen agreed to take part.

Fafara tells Joel Gausten: "When we talked about making a record, it was very much on the top of our heads. She was in a really great place personally and with us. She's a monster on stage, and she's an absolute monster in the studio. I don't know a lot of bass players on a record that's going to be of this calibre who can just go in and wail on it like that.

"She brings her own style to things, and she's a bit of a mediator between us as well. Not so much now, because there's never any conflict.
