Sugarland will return to Indianapolis on Oct. 28 for a free concert to conclude their 2011 Incredible Machine tour. The full-band show will be held at Conseco Fieldhouse in downtown Indianapolis. According to a press release, Sugarland will honor all previous ticketholders, regardless of refund status, for their canceled Aug. 13 date at the Indiana State Fair. Ticket distribution will start with a first-come, first-serve presale for previous ticketholders, beginning Monday (Oct. 10) at 10 a.m. ET. Remaining seats for the general public will be released on Oct. 15. Contributions will benefit the Indiana State Fair Remembrance Fund in honor of the seven people who died when a storm struck the fairgrounds just prior to the duo’s Aug. 13 concert.
