Country duo Sugarland will end its Incredible Machine Tour with a final stop back in Indiana for a free Oct. 28 concert at Indianapolis’ Conseco Fieldhouse. The intention is to honor all previous ticketholders for the Aug. 13th Indiana State Fair show, which ended in tragedy when the stage collapsed and killed seven people. Contributions to the Indiana State Fair Remembrance Fund will be accepted throughout the night. Special guests will be announced at a later date.
