Epic Day is the nineteenth[1] studio album by the Japanese rock duo B'z. It was released on March 4, 2015, more than 3.5 years after their previous studio effort, C'mon,[2] their longest gap between studio albums. It came after a hiatus in which the members released solo projects, including vocalist/lyricist Koshi Inaba's Singing Bird and guitarist/composer Tak Matsumoto's New Horizon.
The album comes in four versions: the regular edition with the 10-track CD; the analog edition with a download card; the limited edition with a bonus live DVD; and the Live-Gym 2015 Edition with live goods.[2][5]
It was the first time that a B'z album had been released in the vinyl format since the band's early days.
