We're proud of everything we've achieved, with your help, and we want to end the band history on a high note instead of losing focus, interest and drive.

Before parting ways as a band we will perform a few goodbye shows; we also want to record a DVD to serve as a memento of the good times we've had.

[32][33] However, when the recording of the band's debut album In This Moment We Are Free – Cities started, Bovio and Van Giersbergen "wanted to take very different directions when it came to the sound and approach of the vocals".

Bovio made her departure official on April 11, 2017, stating "I'm truly devastated, because I'm a huge fan of Anneke and every single member of the band; they're all incredibly sweet people, as well as top notch musicians.
