nano.RIPE is a Japanese pop rock band that's been around since 1998, starting out as a scrappy indie outfit. They put out a single and three albums on their own before landing a deal with Lantis in 2010.

The band's core is Kimiko on vocals and guitar, and Sasaki Jun on guitar. Over the years they've cycled through bassists and drummers—Abe Nobuyuki handled bass duties at one point, while both Shinn and Aoyama Yuuki have taken turns on drums. The lineup has shifted enough that calling them a four-person band now might not be current depending on when you're reading this.
