Evolution and Experimentation - Ryosuke Yamada's milestone 1st CD single! Following his first full album "RED," Ryosuke Yamada returns with a solo single that fully embodies his growth as a performer and his flair for entertainment. The groove that freely shifts between cool restraint and fiery passion captures the essence of Yamada's artistry, and the vocal work - condensing a rich sense of drama into a single song that could only be realized in a solo project - is a must-hear. The common coupling track "High High High" is a dance tune with an addictive melody and beat, showcasing a sharper edge in both sound and visuals unlike anything seen in his previous solo or group works. Each edition also includes unique coupling songs, offering a vivid glimpse into Yamada's artistic "present." [Regular Edition] includes a three-panel, six-page lyric leaflet.
