“4” marks the return of one of Japan’s hottest rock bands, SPYAIR. After the band reached the dizzying heights of fame in Japan, including sold out nationwide tours and their biggest single so far, “IMAGINATION”, making the top ten in Japan’ Oricon Weekly Single and achieving over 16 million views on YouTube, vocalist IKE suddenly announced on Twitter that he would quit the band following a medical condition with his vocal chord. SPYAIR’s bright future became unexpectedly murky.
“4” is the first album from SPYAIR since returning to music and includes an extra 12 pages of liner notes, lyric translations and an interview with all four band members about the production of the album and the moment the band nearly split apart, exclusive to this edition of the album. It also includes three bonus tracks for CD, previously unreleased outside of Asia, including B-side track “JUST LIKE THIS 2015”, and two live recordings of popular tracks “Genjyou Destruction” and “LAST MOMENT”.
