Earl Root (Root Cellar Records) is still in business but he is mostly on eBay: rooty is his moniker.
Let It Be is still operating on eBay too, although I don't know his moniker.
Know Name still has a store front (Richfield on S. Lyndale), as does Treehouse (formerly Oarfolkjokeopus) Records on Lyndale in Minneapolis, and Eclipse Records is now back, relocated to University Avenue in St. Paul, not far from Porky's. They'll also be featuring local talent instore. Finally, the Electric Fetus is still doing LPs at their store by Franklin and 35W.
