In retrospect, it seems like a supergroup. Drummer Tony Leone has joined The Chris Robinson Brotherhood. Glenn Patscha has been playing keyboards with Ry Cooder and been working with Sheryl Crow, Roseann Cash and Los Cadillacs Fabulosos. Byron Isaacs has joined The Lumineers on bass. Fiona McBain is a founding member of The Big Bright and of esteemed jazz-folk duo Then There Were Two. Guitarist Jimi Zhivago has worked with Glenn Hansard and Kim Taylor and has scored numerous films and documentaries for PBS. And Amy Helm has embarked on a successful solo career, with a new album just released by Yep Roc.
