Sugarland won CMA duo of the year in 2010 Associated Press photo Sugarland's 2010 album "Incredible Machine" received less than incredible reviews and above-average sales. But the country duo still plans an arena tour, with a May 7 date in the Twin Cities. Jennifer Nettles and Kristian Bush haven't announced any specific venues except for the opening night on March 3 in Houston's Reliant Stadium for the livestock show and rodeo. The tour will continue through October. Opening acts will vary but will include Sara Bareilles, Little Big Town and Matt Nathanson. Sugarland last performed in the Twin Cities in April 2009 at Target Center. The duo has scored five No. 1 country tunes. "Stuck Like Glue," the first single from "Incredible Machine," got stuck at No. 2.
