Ticket King Milwaukee will have Sugarland Summerfest tickets! It was just announced today that Sugarland has been added to the 2011 Summerfest lineup. How exciting! Summer feels so far away with all the snow that surrounds our office, but it will be here before you know it. Sugarland’s most recent album, The Incredible Machine, came out in October of 2010 and sold over 9 million copies. Milwaukee country fans will not want to miss out on this concert.
