At a live venue in Fukuoka's Tenjin district, passionate fans are well prepared to record every second of Rev. from DVL's performance — cameras in one hand, notebooks on the knees and penlights in the other hand, all the while with their video cameras running on tripods.

Their eyes are pinned to the performance by the 13-member girls' idol group, who are rising in popularity in Fukuoka. The name doesn't roll off the tongue, but it has meaning: "Rev." is short for "revolution" and DVL stands for dance, vocal and love.

The concert begins with an up-tempo tune as the girls, ranging in age from junior high school to university students, sang and danced in unison. Another of the group's hits, "Ainikinshai" ("Come see me"), includes lots of Fukuoka-related terminology in its lyrics, such as references to Hakata's famous Dontaku and Yamakasa festivals, as well as phrases in the local dialect such as "mattoruken" ("I'll be waiting").
