ASTRO is set to hold a solo concert called Stargraphy, with former member Rocky rejoining the group for the event, as confirmed by their agency Fantagio on April 14. In a statement, Fantagio expressed that after discussions, they decided to invite Rocky to participate in the long-awaited concert under the ASTRO name. The collaboration between ASTRO and Rocky aims to create a stage that evokes fond memories for both the group and their fans, known as AROHA. Rocky will perform alongside the current members on songs he was part of previously.

Fantagio emphasized their dedication to making this solo concert a special and unforgettable experience for ASTRO, Rocky, and their fans who have been eagerly anticipating it. They urged fans to continue showing their love and support for both ASTRO and Rocky. Having debuted with ASTRO in 2016, Rocky departed the group in February 2023 after his exclusive contract ended. Following his exit, he founded his own agency, One Fine Day Entertainment, to pursue solo endeavors.

Fantagio also revealed the concert poster featuring the outlines of all six ASTRO members, including Rocky and the late Moonbin, who tragically passed away in 2023.
