An under the weather Billy Corgan has revealed that Smashing Pumpkins are currently at work in the studio with uber producer Rick Rubin in a post to Instagram.
I often express admiration for Rick Rubin's body of work as a producer. Face it, he's had a hand in on some of the biggest albums of all time and you can't deny that it's a pretty big deal to work with the man. (Hell...Sabbath has recruited him to helm their new album and first full-length with Ozzy since Never Say Die)
