This is a recording of a live performance at Yokohama Arena from ASIAN KUNG-FU GENERATION's first arena tour held from the fall of 2006 to 2007. For the band, who had always toured mainly at live houses, performing at a venue with a capacity of over 10,000 was a tremendous challenge, but they cleared this hurdle in an ideal way. The band's all-standing setup, the band's sound that created a bigger groove, and the audience's willingness to respond to the band's new challenge all came together to create a performance that is vividly conveyed in this album. This is a rare moment in which the band, who have always focused on the theme of "connection," demonstrate their full potential as a live band. The rehearsal documentary is also a must-see, offering a glimpse of the trials and errors of their first arena tour.
