With heavy hearts, we regret to announce that we will no longer be appearing on the Civil Unrest tour this June with our friends in Ill Nino, due to unforeseen issues with immigration in the USA. This is a huge disappointment, but a situation out of our control, so we hope you understand.

We fully support our friends in Ill Nino and the entire Civil Unrest Tour line up and wish them the best as they continue on this tour without us.

This is unfortunate because the band was supposed to be filmed during this tour for their upcoming documentary. We’re curious to know if they will try again for another tour or come up with a plan B to film different footage.
I’m sure we’ll find out soon enough!
