Ticket sales for the two-day Seoul concert to be held on August 9-10 began through Interpark on the 18th at 8 PM KST, and fans immediately flocked to the site, leading the server to crash. The ticketing server was up and running again after an hour delay, and the concert quickly sold out.
Woollim Entertainment stated, "We are thankful for the great interest in the Seoul concert of INFINITE's world tour, 'ONE GREAT STEP'. As much as fans' expectations are high, there is just as much pressure, but INFINITE is planning to bring a totally new stage with their live performances."
INFINITE will kick off their 'ONE GREAT STEP' with a two-day concert in Seoul's Olympic Park and move on to other countries in Asia, including but not limited to Japan and China, the States, South America, and Europe.
