K-pop rock band Xdinary Heroes will release its first full-length album, “Troubleshooting,” on April 30, the band’s agency, JYP Entertainment, said Friday.

The album release is the latest addition to the band’s list of scheduled comeback activities under the “Xperiment Project” title. Under the project, Xdinary Heroes will hold a series of concerts named “Closed ♭eta” and release two full-length albums.

The band will kick off “Closed ♭eta” with three concerts on April 19, 20 and 21 at the Yes 24 Live Hall in Gwangjin District, eastern Seoul.

The “Closed ♭eta v6.0” concerts will be the first of many, with the band slated to hold more performances in June, July, August and September. The band will release a second full-length album after the “Closed ♭eta” concert series ends.

Meanwhile “Troubleshooting” comes six months after the band’s fourth EP, “Livelock,” dropped in October last year.

Its title continues the band’s pattern of naming their albums after commonly used terms in computer programming. Xdinary Heroes’ first three EPs were “Hello, world!” (2022), “Overload” (2022) and “Deadlock” (2023).

A teaser video announcing the album was uploaded to the band’s social media pages at noon on Friday.

Xdinary Heroes debuted in December 2021. Its six members are bassist Jooyeon, drummer Gunil, vocalist Jungsu, guitarists Gaon and Jun Han and O.de on keyboards. Its name, Xdinary Heroes, is short for "extraordinary heroes," symbolizing that anyone can be a hero.
