The awesome job of being a mother is impressive enough. But how about being a mother, and a rock n’ roll icon? An astonishing number of artists have managed the balancing act of family life and public life over the years, perhaps not getting the credit they’re due. Which hopefully will change sooner rather than later. An indie documentary called Rock N Roll Mamas celebrating the trials and triumphs of musical motherhood is making it’s way around the film festival circuit this year. And while it hasn’t yet screened locally, we’re doing our part on The Key on this Mother’s Day by saluting a half-dozen of our favorite rock n’ roll moms. It goes without saying that we’ve missed countless artists with offspring, and please let us know who they are in the comments.
