In the page's words:

We are KollektivDummgehen - music lovers, night people and free spirits from Cologne who have dedicated ourselves to the controlled loss of control.
Our sound moves between ecstasy and escapism, between bass and consciousness.
We celebrate the collective letting go - without pigeonholes, without dogmas, with respect and attitude.

For us, going stupid means:
Celebrating without filters. Dancing without boundaries. Living without constraint.
With irony in our name and our hearts in the right place, we play in spaces where there is room for everyone.

Come and go stupid with us - it might be the smartest thing you can do.
