Around 4 p.m. this afternoon Sonar–the club Lonnie Fisher co-opened in Canton in the summer of 2001, which opened at its 407 E. Saratoga St. downtown location October 2003–announced via its Twitter feed and Facebook page that it was shutting down immediately. The two messages–here and here–claim that the venue’s liquor license and corporate charter have not been renewed, forcing the closure. As of 5 p.m., Sonar’s web site was still up and active with no mention of shows being canceled or moved, including this evening’s Talib Kewli show. City Paper will convey more details as it finds them out.
