On September 27, BLITZERS announced the news that they will be holding their first fan concert in Korea, 'A to z', through their official SNS. The poster that was released, along with the news of the performance, has an eye-catching vintage design that resembles a paper cutout of the members of BLITZERS surrounded by letters of the alphabet. 

Dressed in casual styling and flashy colors that create a hip environment that highlights each member’s personality, BLITZERS are expected to create special memories for their fans through 'A to z'. 

BLITZERS’ first fan concert in South Korea, 'A to z', will be held at Mary Hall Grand Theater at Sogang University on October 28. In addition, the show will be live-streamed online around the world.
