IS:SUE to Release First Full Album 'QUARTET' as a Four-Member Group on May 20

Universal Music LLC has announced that the girl group IS:SUE will release their new album 'QUARTET' on May 20, with pre-streaming available from April 6. This marks the group's first full album to be released with the four-member lineup, which includes the youngest member, RIN, who returned from a hiatus in February.

The album's concept is 'Haven’t you heard? IS:SUE “4 people, 4 colors, a diverse and heterogeneous quartet, a perfect harmony played by IS:SUE”.' Alongside a diverse range of new songs unique to IS:SUE, previously released tracks such as 'SHINING' and 'Phase' will be newly recorded as four-member versions.

The lead track, 'Quartet,' is a song that encapsulates the group's charm, their journey so far, and the bond between the members.

The product will be available in a total of eight formats. Limited Editions A and B will come in digipak packaging, each including a different original photobook. The Fan Club Limited Edition will feature special 7-inch paper jackets with individual member solo covers. Furthermore, the UNIVERSAL MUSIC STORE Limited Edition will include a DVD with footage from the 'IS:SUE Special YouTube Live Show' held on February 12, which was their first performance as a complete four-member group.

Additionally, IS:SUE is scheduled to hold the final performance of their first national tour, '2026 IS:SUE 1ST TOUR FINAL - IS:SUE IS COMING,' on May 24 at the Tokyo Garden Theater, which will be their largest venue to date. Fans are eagerly anticipating both the album and their live performances.
